Half Dimes have the same general designs as larger United States silver coins. Authorized by the Act of April 2, 1792, they were not struck until February 1795, although some were dated 1794. At first the weight was 20.8 grains, and fineness .8924. By the Act of January 18, 1837, the weight was reduced to 20-5/8 grains and the fineness changed to .900. The weight was later reduced to 19.2 grains by the Act of February 21, 1853. Half Dimes offer many varieties in the early dates.
