1937-D Boone Bicentennial. MS-68 (NGC).Gorgeous silver gray surfaces with vivid reddish-gold and magenta highlights confined to the borders. So smooth as to be virtually pristine, the surfaces allow ready appreciation of billowy satin luster and fully impressed devices. This important condition rarity comes down to us from a net mintage for distribution of just 2,500 coins, one of the lowest in the Boone Bicentennial commemorative half dollar series of 1934 to 1938. Certainly among the finest examples of the 1937-D that we have ever offered, and highly recommended for inclusion in an advanced collection.
