1916 Proof Dime Pattern - J-1794a

Coin Details

Description

A sub-variety of the J-1794 Mercury dime pattern, distinguished by the "a" suffix that indicates a different composition or die state from the primary J-1794 entry. Sub-variety designations in pattern coinage typically denote pieces struck from the same dies in a different metal — for example, a copper or aluminum striking of dies intended for silver production. Striking patterns in alternative metals served dual purposes: it conserved precious metal during the evaluation process and allowed comparison of how the design rendered in materials with different physical properties, such as hardness, ductility, and reflectivity. Weinman's Mercury dime design was praised for its classical restraint and sculptural quality, and the pattern sub-varieties document the Mint's assessment of these qualities across different media. The "a" suffix places this piece in the secondary tier of the pattern sequence, after the primary J-1794 striking but before the more distant "b" variant, suggesting a close compositional relationship to the main entry.

Rarity Notes

R-7 (Extremely Rare). Sub-variety dime patterns are scarce, with most known in very small numbers.
