1866 Proof Nickel Pattern - J-505

Coin Details

Description

Nearing the end of the standard Shield Nickel composition series, J-505 tests one of the final conventional alloys in the sequence before the series transitions to even more unusual formulations. The pattern's proof surfaces exhibit the characteristic appearance of whichever specific alloy was used — some late-sequence compositions produced coins with distinctive surface textures, unusual toning patterns, or atypical weight and feel that immediately distinguish them from standard copper-nickel examples. These sensory differences would have been immediately apparent to the Mint officials evaluating the specimens, reinforcing the advantage of the adopted composition in terms of visual appeal and tactile familiarity.

Rarity Notes

R.6 to R.7. Estimated 10-15 examples survive.
