1938 Oregon Trail Memorial. MS-68 (PCGS).The exceptional quality of this commemorative half dollar commands attention as it is one of just three examples at this state of preservation. Satiny luster throughout and the peripheral toning consists of pale gold with the balance satiny silver. The strike is full and complete. However, what sets is 1938 Oregon Trail Memorial commemorative half apart from many is the virtual perfection of the surfaces. Given that a mere 6,000 were struck, it is indeed incredible that any survived in this superlative grade level.
