***Auction Highlight*** PCGS 1938-s Oregon Trail Old Commem Half Dollar 50c Graded ms68 By PCGS. Highlight of the Entire Auction. Up for auction is one of the finest known 1938-s Oregon Trail Memorial graded ms68 by PCGS, near Top Pop, 2nd finest known. Boldly lustrous surfaces are framed by intense gold, pink, and emerald peripheries while the centers are essentially brilliant. Sharply struck and attractive, this superb Gem is among a very exclusive group of coins that can boast of such remarkable quality; indeed but a single example grades finer at PCGS, and that only by a plus designation. The 1938-s is from a scant net mintage of just 6006 coins. This example is tied for the 2nd finest known. The last time an ms68 came to auction in 2016 it sold for $6463 and in 2015 for $7050. The lone ms68+ has never come to auction, but trends $20,000.
