The 1792 Silver Center Cent pattern, Judd 1 (the 10th edition of
United States Pattern Coins by J. Hewitt Judd, edited by Q.
David Bowers), is one of 14 examples confirmed to exist.
The 1792 patterns reflect the first attempt by the U.S. government
to establish a national coinage that was convenient to use.
The Mint Act of April 2, 1792, stipulated the weight of cents at 11
pennyweights, or 264 grains of pure copper.
Chief Coiner Henry Voigt recommended including a silver plug in a
more conveniently sized planchet. Toegether the two metals would have
the same intrinsic value as the originally envisioned larger copper
piece. Voigt's proposal was not adopted, though experimental pattern
pieces were struck.
For these patterns, a silver plug worth three-fourths of a cent was
inserted into a tapered hole in the copper portion's center. The
silver plug flattened out when the entire assemblage was struck on the
Examples of the Silver Center cent are known to exist with the
silver plug absent.
Voigt's personal journal, according to Heritage's auction lot
description, indicates the first Silver Center cents were struck on
Dec. 17, 1792, with Thomas Jefferson reporting the following day by
letter to President George Washington alerting him to the production.
