The 1972 U.S. Mint Proof Set is a beautifully produced five-coin collection struck at the San Francisco Mint, featuring the exceptional mirror-like finish and sharp detail that collectors expect from modern U.S. Proof coinage. The set includes the Lincoln Memorial Cent, Jefferson Nickel, Roosevelt Dime, Washington Quarter, and Kennedy Half Dollar, all bearing the "S" mintmark. Each coin was struck multiple times using specially polished dies and carefully prepared planchets, resulting in brilliant reflective fields, crisp design elements, and, on many examples, attractive cameo or deep cameo contrast. The coins are housed in a protective hard plastic lens and packaged in an official U.S. Mint envelope for long-term preservation. With a mintage of 3,260,996 sets, the 1972 Proof Set is particularly notable because some sets contain the desirable 1972-S Lincoln Cent with the rare Doubled Die Obverse variety, making this issue especially appealing to collectors. Combining outstanding craftsmanship, historical significance, and the potential for valuable varieties, the 1972 Proof Set remains a popular addition to any modern U.S. coin collection.
