Wouldn't you love to own the best quality coins available? You can, with U.S. Mint Proof Sets! What is a Proof Set? It's a specially made, premium-quality set of coins containing one of each denomination issued by the U.S. Mint for that year. Proof coins are produced in very small quantities compared to regular-issue coins. First, the Proof dies are thoroughly buffed and polished, and repolished frequently during production. Then, carefully selected coin blanks are individually fed into a specially modified coin press. Each coin is then struck at least twice, at slow speed and with extra pressure. The result of this process is the distinctive and beautiful frosty Proof appearance of sharply struck design images against mirror-like surfaces. Because they feature the finest U.S. coins available anywhere, Proof Sets should be a part of every collection. We've repackaged the coins in a protective Capital® holder at no extra cost to you. 128,800 minted. Order yours today!
