David Hall: The sorid tale of collector explotation by the distributors of the Boone commemoratives, specifically C. Frank Dunn, came to an end after the 1938 issue. The coins from the Philadelphia, Denver, and San Francisco Mints were sold as a three coin set for a discounted (from the previous year's prices) of $6.50. Only 2100 sets were sold as the public was pretty feed up with the commem market. All three 1938 issues are about equal rarity, though the 1938-D is actually a little more available than the 1938 ad 1938-S. The 1938 is the rarest of the three in MS67 or better condition. The typical 1938 has satin like-luster and fairly good eye appeal.
