Description
J-498 occupies a position in the final third of the Shield Nickel composition series, among the patterns that explored the furthest reaches of alloy experimentation. The design's consistent use across all these variants has provided modern researchers with an unparalleled opportunity to study how different metals respond to identical die conditions. X-ray fluorescence analysis of surviving specimens has revealed the precise metallic formulations of many patterns in the series, adding scientific data to the numismatic record. Some compositions prove to be quite unexpected — certain pieces that appear similar to standard copper-nickel under visual inspection reveal unusual trace elements that suggest the Mint was testing proprietary alloy formulations proposed by various metal suppliers.
Rarity Notes
R.6 to R.7. Estimated 10-15 examples survive.
