1937-S Walking Liberty Half Dollar. MS-67+ (PCGS). CAC. With nearly perfect surfaces and strong visual appeal, it is little wonder that this lovely coin ranks among the finest 1937-S half dollars known to PCGS. Dusted with light iridescent sandy-gold toning, both sides are further enhanced by an impressively sharp strike that is full in virtually all areas. One of the rarer middle date Walking Liberty half dollars, the 1937-S is more challenging to collect in Mint State than the 1936-D, 1939-D, 1939-S and 1940-S, not to mention all Philadelphia Mint issues from 1934 to 1940. Few are as well struck overall as the present example, and even fewer are as expertly preserved. A beautiful, conditionally rare Superb Gem that would do justice to an advanced collection of this popular 20th century series.
