Hey folks, I came across this recently, and was intrigued by the rim being upset, but still having no detail. I really looked hard, but did not find any artifact of a design under magnification - including denticles which I assumed would be at least slightly visible even after manipulation. It weighs 9.85g as shown below. I searched Numista for coins in the weight range of this, within a 0.5g tolerance. I think the most likely answer is the Argentina 2 centavos - but it must be one of the coins that is around 10g when fully intact if it is the case that this was filed down for whatever reason. This link is a lot of all candidates. https://en.numista.com/catalogue/in...g=&m=5&f=&t=&w=9.84&mt=&g=&se=&c=&wi=&sw=&p=2 Thanks a bunch, Evan
The new and shortened list from Numista based on the diameter is interesting. Obviously not one of the essais, so there’s only a small number of items it could be (at least in the date range I specified) Sure could be, but what is more likely? I assumed coin but I suppose there is no real distinction to be made
Exactly how? Where you find something often provides clues to identify things. Like, "found at construction site." verses "found with miscellaneous foreign coins." or "found with mixed batch of US coins." Get the picture?
Some local jeweler's have XRF analyzers and could give you the metal content. Also, local colleges might have a lab that could test it. All of this would be for fun and education, not to mention future contacts. If it were found with British coins, then I'd be looking at the metal used for making those. Let us know how it turns out.
