Random title: Chop Mark
Explanation: Oriental marks or characters stamped into previously made coins, often found on silver trade dollars and other precious metal coins. When coins were used for trading purposes, an oriental assayer would test a piece of the coin for purity. If it met his approval he would stamp his mark into the coin indicating to others it was pure and accurate weight. Today some collectors specialize in 'Chop marked' coins. However, for many coins the chop marks may hurt the value
