1921-D Morgan Silver Dollar. MS-66+ (PCGS). CAC. Features the attractive and distinctive toning seen on some other high end examples of this issue, partially untoned centers with a mottled iridescence of amber, olive and teal hues toward the borders. Intense frosty luster covers the entirety of the impressively smooth surfaces. Despite a mintage of over 20 million pieces and prolonged Treasury distribution, this terminal issue is surprisingly conditionally-challenged. PCGS has certified just 14 pieces finer than the present lot, with just a single MS-67+ at the pinnacle, stressing the desirable and exclusive nature of this lovely piece.
