1999 Proof Dollar Pattern - J-2185a

Coin Details

Description

A die or composition variant of the J-2185 dollar pattern, distinguished by the "a" suffix in the Judd catalog that indicates a distinct die state, metallic composition, or edge configuration from the primary J-2185 entry. In the Judd cataloging system, letter suffixes signify varieties that share the same basic die pairing as the parent number but differ in some material respect — typically the planchet metal, edge treatment, or die state. J-2185a may represent the same Martha Washington or Sacagawea design struck in a different composition from the standard manganese brass — copper-nickel clad, pure copper, or another experimental alloy — or it may document a modified die state with additional or altered design elements. The existence of sub-varieties within the J-2185 family underscores the thoroughness of the 1999 dollar development program, which generated multiple versions of each concept for comparative evaluation. Each variant provides the design selection committee with a different perspective on the same fundamental design concept.

Rarity Notes

R-8+ (Extremely Rare). Sub-varieties of modern dollar patterns are typically produced in very small quantities and are among the rarest pieces in the modern pattern series.
