Bought this at a recent small auction for €100. Someone else mentioned it's an "official museum replica" rather than genuine.
Since my expertise is mostly in Romans, I must admit I'm sort of out of my depth with this one. It's not ferromagnetic and the weight checks out at 3.76g, but I am concerned about some of the surface marks.
I hope someone with some more knowledge in these can weigh in and help verify (or not) the authenticity.
Not my area of expertise, but I see nothing out of the ordinary with this one. Post the edges perhaps? In my experience, museum replicas don't look much like the real thing, probably on purpose.
That said, I can't find this issue in silver on acsearch.info - do you have a more complete attribution I can check for?
