ID Needed on Ancient Coin
My mother was given this coin back in the early 70's by an actor who gave it as a tip at the restaurant she was working at. He said it was "worth more than a tip". It is of course fake. But I'm wondering, does it have a real world counterpart? I think it's Greek, possibly a tetradrachm? Antonius Pius? Any help would be appreciated.
Why step over the dollar to get to the cent? Because it's a 55DDO.
