Coin Finishes
The Mint produces coins with various finishes, including circulating, uncirculated, and proof. Different production steps are used to make these coins.
Circulating Coins
Circulating coins are made to circulate among people as they take care of their daily business of buying and selling. The Mint produces these coins without the extra steps used for the other finishes.
Uncirculated Coins
The Mint makes uncirculated coins for saving and collecting. They are produced the same way as circulating coins, but with quality enhancements to create a brilliant finish.
Proof Coins
Proof coins have a mirror-like background with frosted design elements. The Mint uses a special process of manually feeding burnished coin blanks into presses with specially polished dies. Each coin is struck at least twice to bring out the details in the design.
Reverse proof coins feature a frosted background with a mirror-like design.
Enhanced Finishes
Sometimes the Mint makes special enhanced uncirculated, proof, or reverse proof coins. Frosting or polishing is applied to certain areas of the coin to bring out even more detail.
