I'm a little confused by this coin. It's allegedly a Theodosius I RIC 15a, albeit in every description I read it also refers to Theodosius II. Why? Is this a Theo I or Theo II? I can't find out much about this coin. I pulled my ERIC and none of the 15a have the AVGGG on the reverse only AVGG. Does any one have something to add to this puzzle?
