1792 Proof Dime Pattern - J-11

Coin Details

Description

Judd-11, Pollock-12, is the plain-edge proof variety of the 1792 copper disme pattern, distinguished from the reeded-edge J-10 by its smooth, unengraved rim. The obverse carries the same draped bust of Liberty facing left with flowing hair and the legend LIBERTY PARENT OF SCIENCE & INDUS., while the reverse repeats the small eagle perched on a rock within a laurel wreath. The plain edge on this variety may reflect an earlier state of production before the Mint applied edge reeding, or it may represent a deliberate experiment with edge treatments for the new denomination. Edge finishing was an important anti-counterfeiting measure that the early Mint took seriously, and testing both options on pattern pieces was standard practice. The proof character of these strikings is evident in the squared, well-defined rims and reflective fields, distinguishing them from the more casually produced specimens that circulated or were distributed as souvenirs. The 1792 disme patterns collectively represent one of the most historically significant series in American numismatics. Congress authorized the denomination at one-tenth of a dollar, establishing the decimal coinage system that remains in use today. These copper trial pieces preceded the silver dismes that would eventually enter limited production, and their survival provides invaluable evidence of the Mint's earliest die-cutting capabilities under the direction of engraver Robert Birch.

Rarity Notes
