What are US Mint Proof Sets?

Before the United States Treasury strikes new coinage, they do a test run of the new design. This is called a proof strike. Proof sets are packaged and sold via the U.S. Mint, and have been for decades.

These U.S. mint proof sets are widely collected. Each year, new coinage is issued, which means new proof sets are available to the public.

A great selection of U.S. Proof Sets. We hand pick each set to insure that all the coins are in GEM Proof condition with no toning. Our Proof Sets are also priced well below other dealers and come with a full 14 day return policy.
