How can you tell if a coin has been cleaned?

A coin collector or numismatist can tell if a coin has been cleaned by examining the surface of the coin for any obvious alterations or damage. One way to tell if a coin has been cleaned is by looking at the wear patterns and natural patina that occur over time. If the surface of the coin appears unnaturally shiny, polished, or has a glossy look, it is likely that the coin has been cleaned.

This is because the natural patina on the surface of the coin is removed during cleaning, revealing a shiny or glossy surface that is very different than a coin that has naturally patinated with age.

Another way to tell if a coin has been cleaned is by observing any scratches, dents, or other imperfections on the surface of the coin. If these imperfections have been removed or filled in, it is a clear indication that the coin has undergone some form of cleaning or restoration. Additionally, if the coin has had any chemical alterations, such as acid or solvent treatments, these can be detected through chemical analysis or by examining the surface for any discoloration, corrosion, or other signs of chemical damage.

Lastly, if a coin’s details appear too sharp, too well-defined or too fresh, it is often an indication that the coin has been artificially enhanced through some form of cleaning or polishing. Generally, original strikes look more ‘realistic’ as you would expect from a given mint or year. Coins that are too pristine in their detail or design raise questions about their authenticity or whether they have been tampered with.

It is essential to understand that cleaning, restoration or any form of artificial enhancement can negatively affect the value of a coin. For this reason, it is recommended that collectors or numismatists avoid purchasing any coins that have undergone these treatments. Instead, it is best to focus on acquiring coins with a natural patina that has been preserved or those that are in their original state.

This will ensure that you have a genuine and valuable collection.

Do coins lose value when cleaned?

There is no straightforward answer to whether coins lose value when cleaned, as it depends on several factors. If a collector is interested in purchasing a coin with its original patina, cleaning it can indeed decrease its value. The patina refers to the natural tarnish and surface color changes, giving the coin a unique appearance that can affect its value significantly, particularly for rare or ancient coins.

However, if the cleaning process is done correctly and efficiently, it can enhance a coin’s overall presentation, which can increase its value.

The method and materials used to clean a coin can also affect its value. Professional numismatists often recommend cleaning a coin using the right cleaning agents, such as acetone or distilled water. Abrasive materials like toothbrushes, metal polish, or baking soda can scratch or damage the coin’s surface, which can have a severe effect on its value.

Harsh cleaning methods can also lead to the loss of significant details, designs, or inscriptions on a coin, which again can deter collectors from investing in it.

Additionally, the type of coin being cleaned influences its value. For instance, coin collectors typically seek out coins that have rare mint errors or varieties. These coins usually command high prices at auctions and in the collector’s market. Cleaning such coins can significantly reduce their value, particularly if the mint error or variety starts to disappear during the cleaning process.

Cleaning coins can both enhance and decrease their value, depending on several factors, including the cleaning method, materials used, coin type, and collectors’ preferences. Therefore, people looking to clean their coins should research the best cleaning methods that preserve the coin’s value rather than risk damaging it.

How do I know if my Morgan dollar is cleaned?

In order to determine whether your Morgan dollar has been cleaned or not, there are a few things that you can look out for.

Firstly, you should examine the surface of the coin and look for any unnatural or unusual marks or blemishes. Cleaned coins often have a glossy, shiny surface that appears unnaturally smooth and uniform. This is due to the fact that cleaning solutions can strip away the natural patina that develops on coins over time, which can cause the coin to look new or freshly polished.

Additionally, if you’re familiar with the weight and feel of Morgan dollars, you may be able to tell if the coin has been cleaned by its weight or texture. A cleaned coin can feel lighter than it should, due to the loss of material during the cleaning process. Additionally, cleaned coins can sometimes have a rough, grainy texture caused by harsh cleaning techniques or abrasive cleaning materials.

Another thing to look out for is any signs of residue or discoloration on the surfaces of the coin. Often times, coins that have been cleaned will have a slight discoloration or dulling of the surface, due to the residual cleaning chemicals that were used.

Finally, you can try using a magnifying glass or loupe to closely examine the surface of the coin. If the coin has been cleaned, you may be able to see small scratches or markings that were left behind by the cleaning process. These can be difficult to spot without proper magnification, so it’s always a good idea to closely examine your coins before making any purchases or trades.

All in all, there are a number of ways to tell if a Morgan dollar has been cleaned or not. By examining the surface, weight, texture, and any residues or markings, you can get a pretty good idea of whether the coin is in its natural, unaltered state or if it has been cleaned in the past. If you’re still unsure, it’s always a good idea to seek the advice of a professional coin grader or collector, who can help you determine the true condition and value of your coin.

Why do coin collectors hate cleaned coins?

Coin collectors hate cleaned coins because it alters the original surface and appearance of the coin. When a coin is cleaned, it removes the natural patina and toning that has developed over time. This patina and toning is a natural and organic process that occurs to every coin as it ages, giving each coin a unique appearance and character.

Removing this patina and toning alters the coin’s appearance, and the surface of the coin may also be scratched, making it less attractive to collectors.

Furthermore, cleaning the coin can also damage the delicate surface of the coin. Coins are made of metal, and they are often made of soft metals such as copper, silver and gold. Cleaning a coin with harsh chemicals or abrasive materials can lead to scratches, discoloration or even removal of the metal, which can significantly impact the value of the coin.

Additionally, cleaning a coin can also remove important historical and archaeological evidence. Coins are not just valuable collectibles, but they are also critical pieces of historical artifacts. Each coin tells a story during the time it was minted, and by removing the natural patina and toning, it erases valuable historical evidence that contributes to the collective history of humanity.

A cleaned coin cannot tell the same story as an untouched coin.

Coin collectors hate cleaned coins because they are an alteration of the original surface and appearance of the coin, and it can damage or remove important historical and archaeological value. As such, collectors value coins with an original patina and toning as a more authentic representation of history, and thus more valuable.

Can a cleaned coin be graded?

Yes, a cleaned coin can still be graded. However, the grading process takes into account the overall appearance and condition of the coin, including any potential damage caused by cleaning. In fact, cleaning a coin can actually decrease its value depending on the severity of the cleaning and the potential damage caused.

Professional coin graders use a standardized grading system to assess a coin’s condition, including its originality, surface preservation, luster, strike, and eye appeal. They will examine the coin under a magnifying glass or microscope, and may also use specialized tools to check for any signs of cleaning, polishing, or other alterations.

If a coin has been cleaned, the grader will look for any signs of hairlines, tooling marks, or other damage caused by the cleaning process. Even if the coin has been well-cleaned and appears shiny and new, it may still receive a lower grade due to the risk of potential damage.

While it is possible for a cleaned coin to be graded, collectors and investors should be cautious when considering purchasing a cleaned coin, as it may be worth less than an uncleaned coin in the same condition.

Does PCGS clean coins before grading?

No, PCGS does not clean coins before grading. In fact, cleaning coins before grading is strongly discouraged as it may damage the surface of the coin and alter its originality. PCGS is a highly respected third-party grading service that evaluates coins based on their authenticity, grade, and originality.

Their grading process is designed to assess a coin’s condition without altering its surface in any way. They provide certification and encapsulation services for coins that meet their strict grading standards. These graded coins are then sealed in tamper-evident holders that protect them from environmental factors and ensure their preservation over time.

It is important to note that cleaning coins can negatively impact their value, as collectors and investors prefer coins that retain their original, untouched surfaces. Therefore, it is essential to handle coins with care and avoid any unnecessary cleaning or alterations. PCGS does not clean coins before grading, and maintaining the originality of coins is crucial for their value and preservation.

Will PCGS grade cleaned coins?

PCGS, or Professional Coin Grading Service, is a leading third-party coin grading and authentication company in the world. It offers unbiased and accurate coin grading services to collectors, dealers, and investors alike. However, one common question that often comes up when it comes to grading coins is whether PCGS will grade cleaned coins.

The answer to this question is somewhat complicated. PCGS does not have a specific policy against grading cleaned coins, but it does state on its website that coins that have been intentionally altered, damaged, or damaged by cleaning may not be eligible for grading. According to PCGS’s grading standards, cleaning coins can remove the natural toning or patina that results from the coin’s long-term exposure to the environment.

This toning is often an essential part of the coin’s character, history, and aesthetic appeal, and removing it can be considered as altering the coin’s original state.

Therefore, more often than not, PCGS will not grade cleaned coins, especially if the cleaning has caused significant damage or removed large amounts of toning or patina. However, if the cleaning is minimal, has not caused any damage, and has not altered the coin’s original state, PCGS may consider grading the coin.

It is essential to note that even if a cleaned coin is graded, it will likely receive a lower grade or even a “details” grade designation, which indicates that the coin has some form of damage or alteration.

While PCGS does not have a strict policy against grading cleaned coins, it is crucial to understand that cleaning coins can be considered as altering the coin’s original state, and this can affect their eligibility for grading. Therefore, it is always best to consult with an experienced coin grading company like PCGS before cleaning your coins or submitting them for grading to avoid disappointment or damage to your collection.

Are cleaned coins worth anything?

The value of cleaned coins can be a bit complicated as it depends on various factors. In general, cleaned coins are worth less than their uncleaned counterparts. This is because coin collectors who are interested in purchasing coins are often looking for pieces that retain their natural patina and historical authenticity.

Once a coin is cleaned, its natural patina is removed, resulting in a shiny surface that looks brand new. This can cause the coin to lose its historical significance and cause the collector to lose interest in owning it.

However, there are some exceptions to this rule. Coins that are in low grade condition like heavily circulated or damaged coins, may not have much collector value, to begin with, and cleaning them may improve their appearance and make them more desirable to collectors. Additionally, ancient silver coins that have been buried for extended periods may develop a dark patina that is difficult to remove, and in some cases cleaning these coins can actually improve their appearance and value.

It’s important to keep in mind that not all cleaning methods are created equal, and some can cause permanent damage to the coins. Abrasive cleaning methods like using baking soda, harsh chemicals or abrasive polishing cloths can scratch and damage the surface of the coin, which can lead to a decrease in its value.

Therefore, it’s essential to use the right cleaning method and tools, or better still seek out professional cleaning companies or skilled experts to handle the cleaning for you, to ensure that you improve the appearance of the coin while retaining its value.

While the value of cleaned coins may be less than uncleaned coins, there are some exceptions to this rule depending on the condition of the coin itself and the cleaning method employed. Therefore, it’s important to consider your options and seek professional advice when cleaning coins.

What does cleaned mean on a graded coin?

The term “cleaned” on a graded coin refers to any attempts made to artificially improve the coin’s appearance by removing dirt, grime or tarnish. Cleaning a coin can involve a variety of methods such as using harsh chemicals, abrasives, or chemical dips. These methods can remove the natural patina or color of the coin, which is an important factor in determining its value.

While some collectors may prefer a shiny, clean-looking coin, the vast majority of coin collectors and numismatists frown upon cleaning coins. Coin grading services such as the Professional Coin Grading Service (PCGS) or the Numismatic Guaranty Corporation (NGC) typically consider cleaned coins to be damaged, and will assign a lower grade accordingly.

This makes cleaned coins less desirable to collectors and investors, and can also reduce their market value.

In some cases, a coin may be lightly cleaned using gentle methods such as soap and water, or a specialist coin cleaning solution, in order to remove surface dirt or contaminants that may have accumulated over time. If done carefully by a professional, a lightly cleaned coin may still retain its natural luster and color, and may not be considered “cleaned” by grading standards.

However, it’s important to note that any cleaning or tampering with a coin’s surface can leave traces of abrasions or damage, which can be detrimental to its value.

The term “cleaned” on a graded coin refers to any attempts made to artificially improve its appearance. While some collectors may prefer a shiny, clean-looking coin, cleaning a coin can reduce its value and grading. In the majority of cases, collectors prefer to purchase coins in their original, uncleaned state to retain their natural patina and history.

To ensure accurate grading and fair value, it’s important to leave coin cleaning to the professionals.

Is it OK to clean coins before selling?

There are different schools of thought on the issue of cleaning coins before selling them. Some coin collectors and professionals believe that it is acceptable to clean coins to improve their appearance and increase their market value, while others believe that cleaning coins can damage them and decrease their historical and numismatic value.

One argument in favor of cleaning coins is that it can remove dirt, grime, and other environmental contaminants that can accumulate on coins over time. This can improve the coin’s overall appearance, particularly if it is a rare or valuable coin that collectors may be willing to pay a premium for. Additionally, cleaning coins can help to prevent further deterioration of the coin’s surface, which could lead to more serious damage over time.

However, those who are opposed to cleaning coins before selling argue that it can irreparably damage the coin’s surface and patina. For example, using harsh chemicals, abrasive materials, or improper cleaning techniques can leave scratches, scuff marks, or other types of damage on the coin. This can reduce the coin’s historical and numismatic value and make it less attractive to collectors and buyers.

In addition, removing dirt and grime from coins can also remove important historical and cultural contexts that are embedded in the coin’s surface. For instance, some coins may have patina or oxidation that reflects the age and history of the coin, which can provide valuable insights into the time period in which it was minted.

Cleaning the coin can remove this important historical context and make it less valuable to collectors and historians.

Whether or not to clean coins before selling them is a personal decision that should be based on careful consideration of the coin’s value, condition, and intended market. If you are unsure about whether or not to clean your coins, consult with a professional numismatist or reputable coin dealer to get their expert opinion.

What does PCGS genuine cleaning mean?

PCGS genuine cleaning refers to a label that is placed on a coin that has undergone some form of cleaning, either intentional or unintentional, and has been submitted to PCGS for grading. The label indicates that the coin is not graded on its merits, but rather on its condition after cleaning.

Cleaning a coin is generally not recommended by the numismatic community, as it can remove the natural patina and alter the surface of the coin. In some cases, cleaning can even cause damage to the coin, significantly reducing its value.

However, there may be instances where a coin has been inadvertently cleaned or has undergone some form of surface restoration. In these cases, the PCGS genuine cleaning label allows for the coin to be graded and authenticated while still acknowledging the cleaning that has taken place.

The PCGS genuine cleaning label is not considered a grade, but rather a designation that indicates the coin has undergone some form of cleaning. This means that a coin with this label may be worth less than one without it, depending on the extent of the cleaning and the overall condition of the coin.

It is important to note that PCGS does not endorse cleaning coins and encourages collectors to handle their coins carefully and avoid any cleaning or restoration methods that could harm the coin.

How much does cleaning a coin devalue it?

Cleaning a coin can significantly devalue it, especially if it is a rare or antique coin. When coins are cleaned, the process can damage the surface and remove the natural patina or toning that has developed over time. This can lead to scratches, abrasions, or even chemical damage that alters the texture, color, and overall appearance of the coin.

Moreover, cleaning can remove microscopic layers of metal from the surface, which can further diminish the coin’s value. These layers often contain details and embossments that are indicative of the coin’s age and origin, and removal of these layers can result in a loss of historical or numismatic significance.

Additionally, over-cleaning or using harsh chemicals can cause the coin to become brittle, weakened or even corroded. This can lead to further damage, including cracking or completely breaking the coin. In extreme cases, cleaning can even erase part of the design or lettering on the coin, making it impossible to identify or attribute.

Therefore, it is important to understand when and how to clean coins properly. Cleaning should only be done as a last resort, and only with great care and attention. Coins should be cleaned with gentle chemicals and methods that do not damage the surface or remove the natural toning. It is always advisable to seek advice from reputable dealers or coin experts before attempting to clean a coin.

Cleaning a coin can significantly devalue it, both monetarily and historically. Knowing how and when to clean coins properly is crucial to preserving their value and significance.

Do cleaned coins lose value?

In general, cleaning coins can have a negative impact on their value, but it ultimately depends on a variety of factors. For collectors and numismatists, the condition of a coin is a crucial aspect of its value. Properly cleaned and preserved coins are more likely to retain their original condition and appeal to potential buyers, which can increase their value over time.

However, improper cleaning techniques can lead to visible damage, such as scratches or discoloration, which can significantly decrease a coin’s value.

Additionally, many collectors are interested in the history and context of a coin. Cleaning a coin can remove the natural patina and toning that develops over time, which may decrease its historical value. Some collectors also view cleaned coins as less “pure” or “authentic,” as the process of cleaning can alter the original appearance of the coin.

Despite these potential drawbacks, there are some instances where cleaning coins may be beneficial. For example, if a coin is heavily encrusted with dirt or corrosion, carefully cleaning it can reveal details and features that were previously hidden. In cases where the coin’s original condition is already damaged or compromised, cleaning may not have much impact on its value.

Whether or not cleaning a coin will impact its value depends on a variety of factors, including the type of coin, its condition prior to cleaning, and the methods used to clean it. If you are a collector or investor, it is important to do your research and consult with experts before attempting to clean coins in your collection.

In some cases, it may be best to simply leave them as they are, preserving their original appearance and value.
