Glad I quickly flipped through the references for this one!
Nabatea, Obodas II (?) And Hagru
AE Unit (Prutah?)
Jugate busts of king and queen right
Eagle standing left, Nabatean around
There are a few Nabatean bronzes with eagles modeled after the Ptolemaic model, but apparently only one with a jugate portrait. I can't find much on Obodas II, except that Wikipedia mentions his existence was questioned until recently.
See another example on FORVM, it's mentioned that only a few (4-5) of these are known:http://www.forumancientcoins.com/bo...pic=91378.75
Lesson learned: Do your homework before you sell!
