1854 P1C One Cent, Judd-161 Original, Pollock-187, R.4
The design is similar to the large cent then in circulation, but there are no stars on the obverse, and the planchet is smaller--just about 25.4 mm (1 inch), compared with a diameter for the regular large cent of 27.5 mm (1.08 inches). Struck in copper or bronze with a plain edge.
While the measurements above do not seem to be a dramatic difference, it is one that is immediately noticeable. The corresponding weights, of course, differ as well. Originals and restrikes are known. The originals, per Pollock, weigh in the neighborhood of 91 to 100 grains (5.9 to 6.5 gm), while the restrikes weigh around 113-114 grains (7.3-7.4 gm). By way of comparison, a standard 1854 large cent would weigh 10.9 gm when new. PCGS has only certified one piece as a Restrike.
