United States Proof Sets Auction Sale
We have proof sets produced by the U.S. Mint available in all years. Coin collectors can comparison shop for these highly desirable proof coin sets.
United States Mint Proof sets feature coins that are struck using a special minting process to produce coins featuring great detail and a mirror like surface, and made especially for coin collectors.
Proof coins are struck during the minting process at least twice by using a specially polished and treated die. These coins are usually sold directly from
the U.S. Mint shortly after minting at a premium price over the face value of the coins contained in the set.
