Hiya, YOC. Long time no see. Nice (although harshly cleaned) big bronze! The best website for learning about and attributing these is http://ptolemybronze.com/. He even has scanned pages of Svoronos. In general, the most helpful page of his website is this: http://ptolemybronze.com/ptolemy_series.html Where a large number of coin pictures are shown along with attribution information. I'll let you browse the pictures to see if you can ID your coin . You may have a bit of trouble because the letter or symbol between the eagle's legs isn't clear. That's a cornucopia in the left field. Have fun!
I am almost certain that there is what remains of a chi rho between the eagles legs makingit this coin....????? Ptolemy III Alexandria Cornucopia with CHI/RHO and PLAIN (No Control) Series 5 This denomination series consists of 8 coins all with the well-known CHI/RHO leg monogram and corresponding coins with no monogram (rare, not all sizes known). Most references agree that the attribution of all of these coins are to the mid or later part of the reign of Ptolemy III. Sizes and weights shown here are the 'nominal ideal' for the types. Actual sizes and weights may vary somewhat due to the striking and manufacturing technology at the time. The idea here is to present the coins as a coherent series. You may also view these same coins with detailed information about each one elsewhere on the PtolemAE Project web site. We show here the Chi/Rho monogram abbreviated as XP and the plain or no-monogram type as: nm.
Possibly, although it's hard to tell about that monogram. It could instead be something from the Ptolemy IV cornucopia series. It's going to be a "best guess" type of attribution.
Thanks TIF In hand I can make out the cross of the chi rho, so I'll plump for that.....as a best guess.
