The Proof 1942 Walking Liberty half dollar is an historic issue struck at the dawn of the United States official entry into World War II. It represents not only the final Proof issue of the Walking Liberty series, but the last Proof half dollar struck until 1950 when the Franklin series was already underway. 21,120 Proof halves were struck in 1942, though only about half of them survive in grades of Proof-65 or higher.

With its series high mintage, the 1942 is the easiest Proof Walker to locate in all grades up to and including PR-68. The most frequently encountered grades are PR-64 to 67, but even a very few PR-69s exist to keep the Set Registry competition interesting.
