Pius Drachm from Mareotis (Mareote) nome

I just picked this up, it is out of my normal area of architectural types. It looks like in RPC there are only 2 drachm types from this Nome (and 4 types total) - one struck by Trajan with 5 recorded there and this one struck by Pius with 4 noted (plus this one soon.) The only sale I could find was from the Wetterstrom collection in 1990, CNA 13 lot 282. One Trajan drachm, which has the same reverse design, was also sold by CNG a few years ago. I can't find anything else, and don't have access to Dattari plates or Geissen as was suggested to me. Anyone here know if this Nome is more common than sales and RPC would indicate?
