Heraldic Art #40 (1971) Yellowstone Centennial. 925 silver SC50C / NGC MS68

Heraldic Art medal struck by Robert McNamara via his Heraldic Art Company of Cleveland, Ohio, who wished to provide a series of high quality commemorative coins for collectors after the Mint stopped its commemorative program in 1954. This specific piece was issued in 1971 to commemorate the Centennial of Yellowstone's founding as the first National Park. Struck in 0.925 fine silver. This is issue number 40 out of a "regular issue" series of 60 pieces which ran from 1959 through 1978 (an addition 7 "special occasion" pieces also were struck during this time period).
