However => I'm crappy at the PT-Coins (they all look the same to me ) ... other than the weight, I'm lost ... hopefully the dudes sort-out your sweet coins!!
Hemidrachm I think.... 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.
