Very clean front end, I greatly prefer that over the "messy" coin shops. Looks great, thanks for sharing the pics.
Somebody on CU pointed out that that Roman silver piece is an antoninianus, not a “denarius” as marked. To which I explained (since my dealer friend would never make such a mistake): “Yes. That’s not Michael’s holder, but a customer’s. It was in with a loose box o’ stuff that recently came in the shop, which he hadn’t reholdered or priced out yet. Gordian III antoninianii are so common that some of us on CoinTalk and NumisForums affectionately refer to them as “roaches”, but they come nice, usually, and their commonness keeps the price down and makes them one of the more appealing options in cheap Roman silver for that reason. Great starter coins for the novice Ancients collector. I think they’re like the 1921 Morgan dollar of ancient coins.”
What I didn’t show you was his private stash. Might do one or two sneak peeks at a couple of those, if he gets ‘em out, and gives me permission to share.
