I have this coin and one other I bought back in March when I went all crazy like. This was one of those that got added in so that I could share the shipping fees with the one I really wanted. For $15 shipped, it's not a bad coin, just worn. It also has an interesting reverse, and, like Steve says, it is a pond skipper. SEVERUS ALEXANDER AE26 OBVERSE: AVT K M AVR CEVH ALEXANDROC IOVLIA MAICA, laureate, draped and cuirassed bust of Sev. Alex. right, facing draped bust of Julia Maesa left REVERSE: HG M TEREBENTINOU MARKIANOPOLITWN (OV ligate), Hera standing left, holding patera and sceptre. Value mark E in right field Struck at Markianopolis under Legate Tereventinus, 222-235 AD 12.42 g; 26.5 mm Moushmov 732 (Never mind the little green spot on the reverse. It's a piece of clay and I'm too lazy to re-image the coin)
Very nice! My similar confronted-busts coin of Marcianopolis was also a cheapie... Moesia, Markianopolis, Philip I and Otacilia Severa AE Pentassarion, 28mm, 13.5g Obv.: AVT M IOVΛ ΦIΛIΠΠOC AVG M ΩTAK CEBHPAC C; confronting draped busts. Rev.: VΠ ΠPACT MECCAΛΛEINOV MAPKIANOΠO/Λ/E/I/T/ΩN; Serapis standing, holding transverse scepter, hand raised, E to left. Reference: Moushmov 852.
Saying HG suggests you are taking the second letter to be a lower case gamma but the same shape just left of Hera's head is OU ligate. I'd also change (OV ligate) to (WN ligate) for consistency and perhaps also mention that the AP in the city name is ligate. I'm less sure of this but I believe the first letters on the reverse are ligate ΥΠ rather than an H. There is a lot of imagination in some readings on these. http://www.acsearch.info/search.html?id=180623 but this one is clearly HΓ http://www.acsearch.info/search.html?id=511910 so I'd stick in the OY after the HΓ even if the top of the gamma is unclear.
