Thanks for the suggestion MorgansRmine. I guess I'll wait until I have pictures then, although I've been googling images and sites for something comparable looking, and reading responses to other peoples queries.

Sounds like you have a " Texas Cent" -- an alteration. These often have the copper plating stripped off. Error coin writer and researcher.

I know it's tough to try and "diagose" what might be up without photos. Can hardly wait to get my system working again!!
This coin, since it's not magnetic, sounds like a zinc planchet, and I've read some comments online about how zinc easily corrodes and darkens when exposed to environmental things, so I suspect some of that is going on and explains the slate gray/bluish (charcoal gray) tinge and mostly flat/matte non-smooth overall surface and silver color underneath.
I have what I believe is a "quarter" blank (was mixed in with the box of pennies and a bag of varied paper coin rollers. Probably fell out of a quarter one. The blank is magnetic (steel?) and its colour is a bit lighter and lustery than the cent. The blank may have vague struck images on it and looks like it may have a collar and hints of reeding. Will post an image of it too, beside the cent, when I can.

If the blank is magnetic, then it is steel and probably not a real planchet/blank. Could be from a electric box punch out. The cent as Mike mentioned is not a mint error. It is PMD. Probably someone placed a cent covered by leather on both sides into a vise and squeezed to make the coin wider in diameter. The gray showing through is the zinc planchet and the plating comes off because of the stretching it loosens the plating and just falls off. |

Thanks Coop. So PMD means post mint damage I believe (re the cent). Am hoping to be able to scan and post pics anyways by the end of this coming week. By the way, our Canadian quarters ARE all magnetic as far as I know. At least our modern ones are. I just checked a lot of quarters with a magnet and they all stuck. Edited by Dottir

Those and some Cents are steel from Canada. They have been the plague of U.S. soda machines for years. They always stuck to the magnet and no one could use after one got hung up on them.

Yeah, they had trouble with the test steel plated (P) coins and vending machines here too when they first tested them out. People complained about them not working in vending machines and stores had to adjust their machines or something.
Sure is confusing with all the different metals and combinations, especially in single years. Makes it more complicated to ID what variety coin you have and looking for transitional variety errors too. I think I'm going to make little note cards for EACH year with all the varieties and things to check for and refer to them as I check dates. Impossible to remember so much info, especially when new to collecting.

OK then. My scanning is functional again since yesterday and I've been scanning up a storm  Here's a scan of this coin as I promised. It's slate or charcoal gray, no plating, coarse surface. Some silver shows through (zinc. it's non-magnetic) The rims/collar edges look "pushed" outwards from the coin obv&rev surfaces and overlaps the collar area, sticking out and over a bit, leaving a "2 railroad tracks" looking effect. I kind of wonder if someone tried to bezel set the coin, that could explain some of how the collar rims seem forced over the edges? Have a look.   |

the "railroad rim" is also a form of PMD. I'm not exactly sure what caused it, though(probably the beginning of a Texas Cent like mike said). |

Yeah, I'm thinking its been messed with PMD altered now too. Did I forget to mention? by the way, its NON-magnetic, therefore zinc ;) |

Thanks for that info. Someone is sending me a 1943 Steelie. I can
hardly wait to see one for real. Be a great cent for my war years
