1942 Walking Liberty Half Dollar. Proof-68 (PCGS). Outstanding condition rarity for both the type and issue, this impressive Superb Gem offers original silver surfaces enhanced by blushes of sandy-gold iridescence that are more pronounced on the reverse. Boldly mirrored in finish with exquisite striking detail. 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. The present PCGS Proof-68 is surely among the most exceptional known. PCGS# 6642. NGC ID: 27V9. PCGS Population: 88; 12 finer in this category (Proof-69 finest). From the George Schwenk Collection.
