On the other hand, coins that are very old or valuable may decrease in value if they are polished, as this would alter the appearance of the coin and lessen its authenticity. Any coin that is particularly old or rare should be handled with extreme care and should never be sent to a professional to be polished, since this can quickly and severely reduce its value.
For general purpose coins that are not particularly valuable, it is usually ok to use gentle cleaning methods to polish them if desired, although it is important to take extra care in order to avoid damaging the surfaces of the coins.

How do you tell if a coin has been cleaned or dipped?
You can tell if a coin has been cleaned or dipped if you notice an unnatural shine to the coin, a smooth surface on the coin, or a rainbow effect on the surface of the coin. To ensure a coin has not been tampered with, knowledgeable coin collectors recommend using a black light to examine the coin, which can reveal if the coin has been doctored in any way.
Additionally, a magnet test can be performed to check for any metal plating that may have been added to the coin. Plated coins will be attracted to the magnet. Coins which have not been doctored will usually show some age, wear, and patina – all signs that the coin is original.
