Parthia Artabanus II Drachm

Nice pickup, Dave.

FSR's attribution is incorrect.

Several features, including Fred Shore's monogram 80 behind the seated archer's throne*, peg this as a Sellwood 65.36/Shore 365, minted at Mithradatkart, which was one of the eastern mints in the Parthian Empire. The eastern mints, further removed from Western influences and mint controls, produced some wacky stuff. The mint monogram, seen on your coin under the archer's bow, is illustrated at upper right on the chart provided by Alwin here:

Sellwood and Shore attributed these to Gotarzes II. More recently, some specialists have reattributed these to Vologases I.

*The Sellwood 63.13 varieties, also from Mithradatkart, had a similar, though not the same, monogram: Shore's monogram 82 (rather than #80, which is on yours). In addition, the 63.13's feature a similar mint monogram - the one in the left of that same bubble in Alwin's chart - but not the same as yours, which is the rightmost on the chart. FSR's mistake is understandable.

Hey thx. That is exactly the information that I needed. You rock.

Looks like there is a similar piece, both in design and metal here:

As far as I know, Dave, valuation was the same despite the debasement. There may simply have been less precious metal available in the east, or the use of AE for drachms may have been based on local tradition. During this same period as your coin (c. first century A.D.), the drachms of Elymais - further south, at the north end of the Persian Gulf - were also bronze, and - further east - many of the drachms of the Gondopharid Dynasty (Indo-Parthians) were also bronze.
