Mineral Heritage of the United States13.6.1974
The 1974 “Mineral Heritage” se-tenant included the first stamps designed in a diamond shape in the U.S. postal history. Issued to commemorate the importance and abundance of mineral resources to the country, the four stamps were attached to also form a diamond-shaped se-tenant sheet. The stamps pictured petrified wood, tourmaline, amethyst, and rhodochrosite.
The stamps were issued on 13.6.1974 at Lincoln, Nebraska.
Thank you Merja for this wonderful FDC.
