halfcorked New Member United States 6 Posts	Posted 07/22/2014 4:51 pm I have found a 1943-S steel Wheat penny, but it appears that it has some copper in it. It does stick to a magnet, so I'm sure it's steel, but could it be a "mixed alloy" coin? Is this rare? Haven't been able to locate much info on it. Thanks all! * Moved by Staff to a more appropriate forum. * Report this Post to the Staff

halfcorked New Member United States 6 Posts	Posted 07/22/2014 5:15 pm Thanks; but not rust; picture not the best, but it appears to be flaking, but it's not. Coin is dirty; have not attempted to clean it. Report this Post to the Staff
wheatchaser140 Pillar of the Community United States 2368 Posts	Posted 07/22/2014 5:26 pm I'm positive that's rust, flaking or not. The composition of the steel cent is 99% steel and 1% zinc (the outer coating). The pitted, red area is the reaction of iron and oxygen, aka rust. There is no such thing as a "mixed-alloy" steel cent. Wait for some other members to chime in. I'm sure they will have similar opinions.

Hflirn Pillar of the Community United States 586 Posts	Posted 07/23/2014 7:38 pm From 1943 there were a couple experimentals treated with a substance called Cromak. Also, some went through an Irididite Process from the Rheem Mfg Co. There were some made from stainless steel (don't quote me) but I think made at Denver Mint. There were 4 different purities of zinc supplied by the Atlantic Zinc Works to the Philadelphia Mint. With all this being said I'll have to agree with the above comments based on appearance. If you want to take a chance and put up I think $30 bucks on a metallurgy test that is entirely up to you. Report this Post to the Staff
