Description

Judd-312a is a metallic variant of the J-312 two-cent pattern, struck in a different alloy from the standard version. The "a" suffix in Judd catalog numbering typically denotes a composition change while maintaining the same die combination. This piece shares the identical obverse and reverse designs of J-312 but was struck on a planchet of different metallic content, allowing direct comparison of how the same design appeared in different metals. Such compositional variants were valuable to Mint officials evaluating which alloy would best serve the new denomination in terms of striking quality, appearance, and durability.

Rarity Notes

Rarity-7. Scarcer than the standard J-312. Estimated 5-8 specimens known.
