Yeah, you really need to check out his other threads. https://www.cointalk.com/threads/key-date-canadian-dime-found-in-junk-bin.402874/ https://www.cointalk.com/threads/not-bad-for-20-cents.402875/
I would be surprised if stainless steel would corrode like that, not to mention the scratches give me the impression that the metal is relatively soft. If the coin had the same volume as a new Morgan dollar, then yes, the weight you measured would put the density very near the upper limit of the density range for stainless steels. I am going to make an assumption that with the "wear" and chipped rim, that the volume of your coin would be measurably less than that of a new Morgan dollar. This would bump the density value up a bit, probably going outside the normal range for stainless steels. Since I don't think you would hurt the value any, can you take a sharp knife and make a test cut to see how soft the metal is? Try to also make a cut in a piece of steel for comparison.
I haven't heard much about fakes being struck from stainless steel, just softer iron. Have you checked whether it's magnetic?
Ditto. It almost looks like lead. Or some kind of pewter-like pot metal. There is that. I agree. While it looks like a counterfeit, it would be an old counterfeit, which was made to pass in commerce at the time. And if that's the case, then it doesn't matter how ugly it is. As a contemporary counterfeit Morgan dollar, it's probably worth just as much as an undamaged real one, to the right collector. This is one of those rare situations where you could actually be better off if it's fake, because a real coin in that condition would be barely worth the silver value, and a contemporary counterfeit might fetch a bit more than that.
Well, lead would be heavier. It’s non-magnetic, and according to my coin guy the only metal that’s reacts like it did to the acid is 14k gold or stainless steel. My bet would be pewter if it’s an old fake
Th The way that your Morgan scratched the way it did would mean that it may have a nickel or white metal alloy to it. I still lean to a lead base. Stainless is too hard of a material to wear the way this has.
No matter what it’s made out of, it looks like it circulated for some time. It fooled a lot of people.
I'm guessing the coin guy in question can justify spending $30 for an acid test kit but not $20K for an XRF.
