{{globalize|date=December 2010}}{{Refimprove|date=December 2012}}The term uncirculated coin can refer to three things: - A coin that is released to the public but not intended for general circulation (i.e. not used for money although it has an actual value) but is available through a mint or through a local coin dealer. Most uncirculated coins of this type are either commemorative coins made of gold, silver, or platinum bullion coins (see picture below); actual uncirculated rolls or bags of coins (see next bullet and picture below); special coinage sets; or proof sets (see pictures below).
- A coin that has been officially graded as in "Mint State 60+";
- The process by which a coin is made. The U.S. Mint uses this definition for the uncirculated coins that it sells. For uncirculated coins, adjustments to the minting process are made which result in a more satin-like finish. These include using a higher force during coining, the use of fresh dies, and special cleaning.[1]
