1866 Proof Nickel Pattern - J-483
Strike TypeCoin Details
Description
This Shield Nickel composition variant occupies a position in the mid-range of the extensive 1866 testing series, where the Mint explored increasingly exotic alloy formulations after exhausting the most obvious candidates. The numismatic significance of these mid-sequence patterns lies partly in their documentation of the Mint's thoroughness — rather than selecting the first acceptable alloy, the testing continued to ensure no superior option was overlooked. The Shield design's prominent relief features — particularly the deep horizontal and vertical lines of the shield itself — served as an effective test for each alloy's ability to flow into intricate die cavities under pressure. A composition that failed to fill these fine details produced a mushy, poorly defined coin that would have been unacceptable for a prestigious new denomination.
