1937-D Walking Liberty Half Dollar. MS-66+ (PCGS). CAC.A truly superior Gem sporting coveted approval by CAC. The surfaces remain largely brilliant and feature olive-gold patina that is most intense at the obverse border. The fields are faintly reflective and contrast the richly frosted design elements on each side. One of the scarcer and more underrated middle date Walking Liberty half dollars, the 1937-D is rarer in Mint State than even the low mintage 1938-D.
