Coin of Phillip the Arab

[caiusbeerquitius]

So coins are not artifacts? Jeez. The rule is about looting. Most of these coins come from looting.

And I very much assume that your coins are by that and any other logic unprovenanced, yes.

Or had they been published before you bought them? Where exactly and when and under which circumstances were they found, and if they were excavated properly: which site, which stratum, which ground line? If you do not have these infos, they are unprovenanced.
