Dave Posted January 13, 2017 Report Share Posted January 13, 2017 I've never heard of this experimental before. Discovered it sold last week for a nice amount. http://www.thehistoryblog.com/archives/45447 Quote Link to comment Share on other sites More sharing options...

ccg Posted January 16, 2017 Report Share Posted January 16, 2017 How would one assess lusture on a glass coin? Quote Link to comment Share on other sites More sharing options...
thedeadpoint Posted January 16, 2017 Report Share Posted January 16, 2017 As a nerd for nuclear history (and a coin collector), this part was very cool to read: "Official records indicate Treasury thought the glass coinage would be “too brittle,” but that was just a smokescreen. The real reason was as top secret as it gets. The planned production line glass pennies would have contained traces of uranium oxide that would make them fluoresce under ultraviolet light, a cool and ingenious anti-counterfeiting system. But another project that started in 1942 required every molecule of fissionable material that could be scrounged up, so the glass coins were scrapped and Blue Ridge had to send all of its uranium stock to Oak Ridge for use in the Manhattan Project."

Dockwalliper Posted January 23, 2017 Report Share Posted January 23, 2017 Interesting that Durez Plastics and Chemical, Inc. (North Tonawanda, New York) was one of the companies trying alternative materials for cents. They were located a few miles North of me. The location is now a empty , contaminated, field.

ikaros Posted January 25, 2017 Report Share Posted January 25, 2017 Wow! I never even heard of such a thing -- very, very cool! I don't know about glass per se, but I can imagine there might be a sufficiently tough ceramic out there that could stand up to pocket punishment if they wanted to try that again.
