David Hall: The three 1937 Texas commemorative half dollars were distributed in less quantities (6571 for the Philadelphia, 6605 for the Denver, and 6637 for the San Francisco) than the seven 1934-1936 issues (8911 to 10,007 for the 1935 and 1936 issues and 61,463 for the 1934). They are consequently rarer. However, none of the 1934-1937 Texas commems are rare in Gem condition as they were all well-preserved. The 1937 Philadelphia is the rarest of the three 1937 issues in Superb Gem MS66 or better condition. The typical 1937 Philadelphia Texas has frosty white luster and excellent eye appeal.
