1868 Proof Three Cent Pattern - J-620a

Coin Details

Description

A compositional variant of J-620, this proof three-cent pattern was struck on an alternative planchet. The continued production of suffix varieties this late in the 1868 three-cent series indicates that metallurgical testing remained an active component of the pattern program throughout the year. Each planchet variant provides data about the design's adaptability to different metals, information that could inform decisions about future compositional changes across any denomination using the copper-nickel alloy.

Rarity Notes

R.7 to R.8. Very rare, approximately 4-7 examples survive.
