Let's see if I can stump ya!
Does anyone know the type of steel used in the steel pennies minted for the copper shortage of 1943?
I was browsing a novelty catalog, which features grusome Halloween masks and rubber dog poo Christmas ornaments, but also, a bag of these old steel pennies! I thought they might weld up cool in a can somehow with some powdered contrasting steel. Maybe try to get 'em on edge for a nice linear pattern down the blade... It seems someone once told me they are zinc coated (bad), but I just don't know. That was when I was a kid. Anybody? __________________ Andy Garrett https://www.facebook.com/GarrettKnives?ref=hl Charter Member - Kansas Custom Knifemaker's Association www.kansasknives.org "Drawing your knife from its sheath and using it in the presence of others should be an event complete with oos, ahhs, and questions." |

Yes , zinc coated steel. The steel is probably low carbon and soft so as to be coined easily.

"Production of the war-time cent was provided for in an Act of Congress approved on December 18, 1942, which also set as the expiration date of the authority December 31, 1946. Low-grade carbon steel formed the base of these coins, to which a zinc coating .005 inch thick was deposited on each side electrolytically as a rust preventative. The same size was maintained, but the weight was reduced from the standard 48 grains to 42 grains, due to the use of a lighter alloy. Production commenced on February 27, 1943, and by December 31, 1943, the three Mint facilities had produced 1,093,838,670 of the one-cent coins. The copper released for the war effort was enough to meet the combined needs of 2 cruisers, 2 destroyers, 1,243 flying fortresses, 120 field guns and 120 howitzers, or enough for 1.25 million shells four our big field guns."

Andrew.
I picked up some plating remover from Brownells that would remove that Zinc Coating. I bought some to remove plating from screws. It is not supposed to damage steel. It might be a lot of work but the novelty might be worth it.
