I found this thread from some time back but it doesn't address the silver version and, it says it's a copy:

I believe this one is silver. It weighs 27.15 grams, and is 39.1mm in diameter and 3.09mm thick at the rim edge. So where is an example of an
original with which to compare? This "looks circulated. Which is of course how copies/fakes look. It's not cast, it's struck. And it's heavy. were it brass it would need to be thicker to weigh like it does, in copper it would be awfully close to silver in specific gravity. And it's got it's denticles. Most copies seem to have little detail for those. I take it there were silver repros/copies?
Any thoughts appreciated.
ps, sorry for the misaligned pix... all the pix are of MY coin; not ones from another thread.
