1869 Proof Nickel Pattern - J-690a

Coin Details

Description

A compositional variant of J-690, this proof nickel pattern was struck on an alternative planchet as indicated by the "a" suffix. This piece represents one of the final metallurgical experiments in the Reconstruction-era Shield nickel pattern program. The suffix variant provides a last comparison point between the adopted copper-nickel composition and whatever alternative metal was used for this piece, closing out four years of systematic alloy testing that had accompanied the design experimentation.

Rarity Notes

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