Bicentennial Minuteman 1 Troy Ounce Silver Round

Lovely older silver round commemorating the US Bicentennial in 1976. The obverse shows a minuteman, while the reverse features a ribbon on pole design commemorating the anniversary. While the round bears no assay mark or sign of where it was minted (likely due to it's age) and shows a flat grey finish not normally associated with rounds, the item has been tested and weighed and confirmed 1 Troy Ounce of .999 Fine Silver.
