We do not clean or attempt to remove any dirt on the coins. You will notice this in the photographs. Once you purchase your coin, you are of course free to clean it however you choose but we would suggest researching methods first. It's important for you to understand how some methods of cleaning may detract from the value of the coin or remove the patina often sought after by collectors.

That being said, there are likely some hidden gems in our catalog. Coins that initially appear to lack detail or definition due to dirt may reveal much higher quality upon cleaning.
