I have one more coin to post, from the same source as the Caracalla tetradrachm. I do not own this coin. I think this is a tetradrachm (13.2 grams) of Ptolemy I. The portrait suggests that, but it could also be one of the later Ptolematic kings (II, possibly). This is a very high grade coin. The reverse is atypical of what I have seen for Ptolemy I or II (certainly not from Alexandria). The weight of this coin suggests that it came from a mint further east. Any ideas? Again, any catalog, or references would really help. Thanks
