1868 Proof Three Cent Pattern - J-617c

Coin Details

Description

The third compositional variant of J-617, representing an extensive metallurgical testing program applied to a single three-cent pattern die pair. This "c" suffix variety was struck on yet another planchet type, making J-617 one of the most comprehensively tested die combinations in the 1868 pattern series. The range of compositions tested with this particular design indicates it was a favored configuration that the Mint wanted to evaluate across every feasible metal option before making a final determination.

Rarity Notes
