Unofficial PROVIDENTIAE CAESS

It is a pretty neat coin, decent engraving and pretty nice style. The small size makes it even more interesting.

A more significant (not as far as it is in hand) picture . Compared to Constantine II / Providentiae Caess coin:

[Genio popvli romani]

Here is another interesting one, struck "for" Constantine I, which is an hybrid with an Augustus obverse legend CONSTANTINVS P F AVG combined with a Caesar  faulted reverse legend PROVIDENTIAE CAS (sic).
