1870 Proof Half Dollar Pattern - J-930a

Coin Details

Description

A cataloged die-state variant of J-930, this plain-edge copper half dollar pattern retains the Seated Liberty obverse with raised LIBERTY on the shield and the STANDARD agricultural wreath reverse. Like J-927a, this sub-variety was identified through close die-state analysis of surviving specimens, reflecting the meticulous scrutiny that pattern specialists apply to these extremely rare coins. The variant designation indicates a detectable difference in die characteristics that separates this striking from the primary J-930 listing, whether through progressive die wear, relapping, or a subtle die crack.

Rarity Notes

R-7. Extremely rare, estimated 4-12 examples survive.
