Would love a confirmation from @Kamnaskires as to the type but anyone else is welcome to contribute. Picked this up a few months ago and never posted it.
Came with an older Kraft paper envelope identifying this as Göbl I/1 136. I don't have any modern references to confirm, and all the listings I can find for that particular variety don't seem to quite match exactly this coin in one way or another.
Sasanian drachm of Bahram (Varhran) IV, 388-399 a.D.
AR, 4.1 grams, 25.3x24.5mm, some light golden-reddish toning. I made those measurements myself, the envelope had none.
One of the dies is rotated about 90 degrees counterclockwise (not shown in the photo)
I rather like it, it looks quite nice in hand, considering how old it is!
