This coin long remained doubtful (and at best misattributed) until the 1990s discovery near Paris of a second example with die-identical obverse but a Mars reverse type used by Aemilian (to whose radiates from the mint of Rome they are similar in style and fabric). Despite the French findspots for both Silbannacus coins (current example was found in Lorraine) and his Gallic-sounding name, his brief usurpation must have included dominion over Rome (and little else) where his coinage was apparently made.
