Description

Judd-330a is a compositional variant of J-330, struck in an alternative alloy while using the same die pair. This off-metal version provides comparison data for the J-330 design in a different planchet material. The systematic testing of each significant dime design concept in multiple metals was standard practice in the 1863 pattern program, reflecting both the practical need to evaluate alloy suitability and the collector demand for variety that helped fund pattern production.

Rarity Notes

Rarity-7. Approximately 5-8 specimens known.
