The combination of a lack of legible detail on this piece plus the very uneven coverage from reference to reference makes it impossible to tell the mint of origin for this coin.This coin comes from a large group of Roman Provincial, Byzantine and Vandalic coins which were part of Leopold Hamburger's inventory.
