Contact Us: If you have U.S. coins and need to determine their value, please first try to use the AMC website. If you have modern foreign coins (1940 or newer) or medals and they are made of copper or silver, try using Google images to identify, then eBay completed sales to see what they trade for. If you want to sell your coins and they are greater than $250 in total value, please state so below in the comments section. We will try to contact you by eMail or telephone as soon as possible.
