This bronze coin of Elagabalus has 32 mm. of dimension. The obverse has a clear counter mark which might be unpublished for this sample. Struck at Zeugma-Commagene in Syria, the reverse shows a temple and a peribolis with sacred groves. It weighs 14.28 g. Please post a comment, if you like.
For the countermark, you might look in Manasaryan's Sylloge Nummorum Commagenum. It lists two countermark types:
Can you post larger images with better focus and better lighting? I can't make out the design of the c/m in your small pictures.
Interesting coin. @John Anthony sold several of this reverse type of Zeugma about a year ago as I recall. I picked one up of Phillip the Arab. Sadly the city was destroyed in 256 by the forces of Shapur. COMMAGENE, Zeugma. Philip I and II. 247-249 AD. Æ31, 19.2g; 6h (a nice chunky coin, how about that?) Obv.: AYTOK K M IOYΛI ФIΛIΠΠOC CЄB; Laureate, draped, and cuirassed bust right. Rev.: ZЄYGM-ATЄΩN; Peribolos containing grove of trees, seen in perspective; tetrastyle temple in distance, draped figure within (Zeus?); in exergue, capricorn to right. Reference: Butcher 31c; BMC 35.
Thanks for your collaboration. I could manage to have a couple of scans at 300 and 600 dpi. The coin is worn and needs cleaning. The C/M might be a horse running left. It might be ridden by a knight. watch this, for fun at least.
I recently collected what I consider to be a best-of-type example. Not only is the coin in a nice grade with a beautiful black patina, but it's got a sharp eagle countermark in the perfect place, where it only minimally interferes with the devices...
