I bought this out of a batch of loose ancients at a local coin show several years ago. I think it is Ptolemy II or III, but I cannot tell for sure. Any help is much appreciated .
Heh... twenty minutes ago in another thread I typed instructions on how to attribute Ptolemaic bronzes so I'll paste a link to that post here . https://www.cointalk.com/threads/which-ptolrmy-is-this.341301/#post-3579182 Your coin has significant corrosion though so it may not be possible to accurately nail it down. Posting the size and weight is necessary for these coins.
