The 1973 U.S. Mint 6-Coin Proof Set features all six denominations of U.S. coinage produced for collectors in 1973, beautifully struck at the San Francisco Mint with brilliant mirror-like fields and sharp frosted details. The set includes the Lincoln Memorial Cent, Jefferson Nickel, Roosevelt Dime, Washington Quarter, Kennedy Half Dollar, and Eisenhower Dollar, each bearing the "S" mintmark. Every coin was specially struck multiple times using polished dies and carefully prepared planchets to produce the exceptional quality expected of U.S. Proof coinage. While the official U.S. Mint sold the five-coin Proof Set and the Eisenhower Proof Dollar separately, many collectors and dealers combined them into this attractive six-coin presentation, creating a complete Proof set representing every denomination issued for the year. The 1973-S Eisenhower Dollar was available in both copper-nickel clad and 40% silver versions; this set should be identified accordingly. Complete six-coin sets such as this are highly desirable because they provide collectors with a full representation of the Mint's 1973 Proof coinage in one convenient display.
