1942 Experimental Glass U.S. Cent Goes for $70,500 in Heritage’s Florida Auction

An experimental cent made from glass sold for $70,500 at a public auction held in conjunction with the Florida United Numismatists (FUN) convention in Fort Lauderdale, Florida.

1942 1C Experimental Glass Cent

Graded PR64 by PCGS, this experimental glass cent, sold for $70,500 in a public auction conducted in Fort Lauderdale and online by Texas-based Heritage Auctions

Heritage Auctions presented the all-glass cent on Friday, Jan. 6, as part of its $65 million offering of rare coins and paper money this week. A war between bidders on the phone and floor drove the cent’s selling price to more than double its $30,000 expected value.

Made in 1942 to test as a possible alternative to copper, it is the only intact example known to exist. One other piece has surfaced but it is broken in half.

"This one-of-a-kind cent is a part of U.S. history," said Mark Borckardt, Senior Numismatist and Cataloger at Heritage Auctions. "Collectors love to own unusual specimens, and although glass failed as a substitute for U.S. coinage, this piece represents a unique artifact of the ingenuity and determination of U.S. Mint officials and private industry."

In 1942, the United States Mint researched other materials to make cents because of wartime copper shortages. The bureau also invited private companies to test various types of materials. The experiments were publicized in trade magazines around the country.

"Plastics fabricators, particularly those who made buttons, began to experiment with pieces the size of a cent but the Blue Ridge Glass Company of Kingsport, Tennessee, requested an opportunity to experiment with glass," Borckardt said.

The U.S. Mint had a pair of used dies sent from Colt Manufacturing Co., one of the plastics experimenters, and Blue Ridge obtained tempered, yellow-amber transparent glass "blanks" from Corning Glass Co. However, by the time the glass tests were completed in December 1942, it was too late for the U.S. Mint to consider the material as a viable replacement in making coins. In 1943, the Mint struck cents made of zinc-coated steel.

The 62nd annual FUN Convention is January 5 to 8, 2017 at the Greater Fort Lauderdale/Broward Convention Center.

Heritage Auctions is the largest auction house founded in the United States and the world’s third largest, with annual sales of more than $800 million and over one million online bidder members. To learn more about the company, visit HA.com.

There’s a fascinating discussion in Roger Burdette’s book United States Pattern & Experimental Pieces of WW-II (sic), including trial pieces struck in plastic, fiber composite, and even hard rubber! There are also pictures of some but by no means all at the site uspatterns dot com.

Does anyone know how it was proposed to make coins from a thermoplastic material like glass?

Munzen –

These experimental pieces are briefly described in the 2017 “Red Book” on page 385 in the patterns & experimental pieces section. There are 19 different types of these 1942 “cents” with this design in many alloys of metal & colored plastic & fiber & glass. The website you mentioned is great! Since the government wanted the Mint to save the more important metals needed for the war effort, the Mint put out bids to any company who could produce samples. The glass ones came from the top glass company in the US at the time, Corning company. Why they thought glass would not break back then is beyond me & this specimen is the only intact one known. Ironically, today Corning company makes glass dinner plates that are almost unbreakable! The value of a common piece, other than the glass one, in PF-65 is listed in the “Red Book” as $6,000. So someone really overpaid for this specimen at over twice the estimate. But it is a museum-quality piece & hopefully will wind up in a museum collection some day for all to see & study.
