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 and Uncirculated Mint Sets are widely collected. Each year, new coinage is issued, which means new proof and mint sets are available to the public. We carry a great selection of top quality modern day proof and mint sets all of which come complete with the Display Case, Box and Certificate of Authenticity, or U.S. Mint Set packaging. We hand pick each set to insure that all the coins are in GEM Proof and Brilliant Uncirculated condition with no toning. Our Proof and Mint Sets are also priced well below other dealers and come with a full 14 day return policy.
