Doug, thank you for the reading material. It is most informative and appreciated.. On a side note....I always associated Serapis with John Paul Jones. Thanks for the insite....
I figured you would have something Doug. put a gun to my head I would say the Ptolemy ones at least were to file down the flan because of the striation marks and evidence of the dimple has turn marks in it. It boggles my mind my little AE12 Cleopatra VII's have them as well, you would think they wouldn't have to adjust something that tiny! It proves, since she was the last Ptolemy, that they did this throughout the Ptolemaic period, though, and it looks like eastern mints in the Roman empire as well.
