1804 B-1 Quarter, MS62 Important Mint State Rarity 1804 25C B-1, R.3, MS62 PCGS. CAC. The production of quarters was minimal in the early years of the U.S. Mint, since depositors preferred more convenient silver dollars. The 1804 is a famous rarity, by far the rarest date within the five-year Draped Bust, Heraldic Eagle type. Just 6,738 pieces were minted, slightly more than the 6,146 pieces struck for the even better known 1796. While the 1796 is certainly significant, it is actually more available than the 1804, particularly in Mint State. Weight: 6.74 grams Metal: 89.24% Silver, 10.76% Copper
