1866 Proof Nickel Pattern - J-522

Coin Details

Description

Progressing through the final dozen entries in the 1866 Shield Nickel pattern series, J-522 tests a composition from the outer boundary of the alloy program. The collective significance of these late-sequence patterns transcends their individual numismatic interest — they document the totality of the Mint's investigation into coinage metallurgy during one of the most transformative periods in American coinage history. The transition from precious-metal to base-metal coinage for small denominations was one of the defining developments of the Reconstruction era, and J-522 represents one of the many experiments that underpinned that transition.
