Mintmark, Privy Mark, and Counterstamp Coins
Mintmark
The term mintmark refers to a mark on the original die indicating the location where that coin was struck.
Counterstamp
Pre-struck coins that are subsequently modified by the Mint using a metal punch on a mobile press prior to issue. A counterstamp can be identified as a symbol surrounded by a small circle.
Privy Mark
Struck using a die that has been modified to include a letter or symbol commemorating a special release or event. In order to clearly identify these coins, the privy mark will consist of a letter or symbol with a square surround.
Please note that as many of these products are years old, cards, packaging and capsules may have minor cosmetic damage from their time out and about. Toning may be present.
