Is This Coin Really?

A coin minted by constantine the great. Early fourth century. Is this copper? I assume that it is. And i think it might have had a silver wash over the top at some point. That again, te currency and intentional d valuing of currency is something we need. But what's noteworthy about that coin is that you identified it correctly. It may be with an old sand mould, somebody cut out several circles for the blanks, for the coins. You can still go stand on the spot where that temple operated for centuries.
