I have been going through a coin collection that someone inherited. In one of the bags of coins there were a couple of these. My hunch is this is just a piece of copper that looked like it could be a blank so they kept them. In other words a "slug". Just in case I am wrong and this really is something I shot a photo and am asking for more opinions. The ruler is in mm and the quarter is there for size comparison. It weighs 6.4 grams and is about as thick is the quarter next to it. There is also no rim like a blank planchet has and is smoother than my US LMC blank planchet. It does not stick to a magnet either. So is this just a piece of copper like I suspect it is? Or is it actually coin related? Thanks...Mont
It's hard to say. It may well just be a slug. If it is coin-related it would likely be from other than the United States; in which case, it could be from anywhere. While somewhat interesting, I would say that unless its origins could be more specifically determined it's quite likely not worth more than novelty value.
@JayF You may want to take a look in your redbook and check the weights of a Sacky. The OP said his weighs 6.4 grams
It looks to me like a blank quarter planchet before the nickel would have been applied. It's too heavy, though. A clad quarter should weigh 5.67 grams. Without the nickel I would think it would be lighter. Do coins lose weight when they're stamped?
The copper center and 25Ni75Cu clad layer have nearly equivalent densities, so if it was the same thickness and diameter it would weigh about the same as a standard quarter. Also, coins do not lose any appreciable weight during minting.
I don't think so. Sac & Pres dollar Blanks and planchets do not look like that along the rim. Here is a sample of both from my collection. I am guessing the OP's is a slug or foreign planchet. Here is a unburnished version of a $1 blank and planchet
