It's just a cheap knock-off, but I guess it's made of real silver. https://www.ebay.com/itm/293940028323?hash=item447030e3a3:g:boYAAOSw6AlbM6xa
Well, you don't want your Domitian coins to smell but an AUTHENTIC Nero denarius would smell like smoke!
Packaging, like mailers etc, from heavy smokers can stink. I remember one package I opened and it was like I was a smoker again. This is more of an issue if you are buying books though.
Oh, I get it. Wasn't sure about the smoke reference. We've certainly have had our share of smoke in California the past couple of fire seasons.
