The 1792 silver center cent, one of the most famous of all pattern designs. This was apparently an attempt to make the one cent coin J4/P5
smaller by using a silver plug to handle the bulk of the value 3/4 of a cent with the copper valued at 1/4 of a cent. The plug itself is conical in shape, and the planchets oriented, such that the wider side was used for the obverse. Judd describes these as having obliquely reeded edges but all the examples I have seen have normal vertical reeding.

12. Starr Specimen. Fine 15 PCGS. Seavey collection (1873 Descriptive Catalog #842), Parmelee, Virgil M. Brand in Sept 1899 (journal id #20765), Armin Brand per his notebooks, J.C. Morgenthau (311th Sale, 10/1933), lot 78; Floyd Starr (Stack's, 10/1992), lot 3; later, American Numismatic Rarities (8/2006), lot 13.
13. California Specimen. VG10 Details, Scratched ANACS. A Northern California collector purchased this piece for $400 in 2006. The coin was offered at a police department auction of unclaimed property. Reported in Coin World, January 5, 2009.
14. Unplugged Specimen. SP63 PCGS. Discovered by Anthony Terranova, 1993; Stack's (3/1995), lot 1400. Former Guide Book plate coin. The coin does not have a silver insert and may have been a trial striking before making the Silver Center cents. In his 1984 provenance study, Scott Rubin mentions Thomas Elder's sale of October 1926, lot 1436, where a piece was described as: "1792. Pattern for Silver Centre Cent (freak)." That listing might represent an early appearance of this piece. We have not assigned it a separate Judd or Pollock number as we are not sure if this was deliberate or some kind of mint error in the production of these.
The Dewitt Smith, Brand (journal id #46507) piece is either #3, 4, 5 or 7.
These were also struck in copper and/or billon J2/P2 with just over a half dozen known with the Smithsonian example, the plate coin in Judd, Pollock and Adams & Woodin, being the finest known. The former Seavey (1873 Descriptive Catalog #841), Parmelee, Brand, Norweb coin is the finest collectible example.
There are also 2 blank planchets without the silver plug in the Independence Hall collection.
