Could this tiny (9-10mm)"VICTORIA AVGGG
" AE4 be a coin of the usurper Eugenius, or is this just wishful thinking?

coins of other emperors like Arcadius in my collection
The only obverse legend visible is "DN" on the left and the "G" of AVG on the right. The mintmark on the reverse appears to be T*P. Note that the photo makes the coin look rather silvery (due to reflection) - it actually has a fairly even greyish-green patina.
