- Undated (1942) Experimental Cent. Judd-Unlisted, Pollock-Unlisted, RB 42-53. Injected Molded Area Urea Formaldehyde Resin. Plain Edge. MS-63 (PCGS). 0.69 grams. Pleasant medium brown surfaces seem conservatively graded at the Choice Mint State level. The overall glossy surfaces exhibit a subtly wrinkled texture under magnification, reminiscent of the "orange peel" phenomenon seen on Proof gold coins of the 19th century. This piece is a product of the United States Mint's search for an alternative material to be used for the cent amidst the copper shortage of World War Two. Among the plastics manufacturers solicited for samples was Patent Button Company of Tennessee, Inc. who furnished 25 samples of the present offering along with 25 samples of a darker, general purpose phenolic resin to the National Bureau of Standards (NBS) for testing. While the samples provided by Patent Button Company were blank, all of the samples from competing manufacturers had been struck or molded by dies provided by the Mint, making these unsculpted samples easily distinguishable among the more ambiguous plastic "patterns" of the era. PCGS# 544970.
