1939 Oregon Trail Memorial. PDS Set. MS-68 (NGC).,This is a breathtakingly beautiful, wholly original set with rich tab toning for each piece. The reverses are more evenly and vividly toned than the obverses. With smooth satin luster throughout and eye appeal to spare, this is easily the finest example of this scarce final year PDS set in the Oregon Trail Memorial commemorative series. From a distribution of just 3,000 pieces per issue, and exceptionally well preserved in all regards. (Total: 3 coins)
