I have always had trouble with the Ptolemaic tetradrachms of Hellenistic Egypt, that is telling them apart. One of these four below is definitely one of Ptolemy II from the Gallic shield on the reverse, but the other three I am still uncertain of. I'd like to pin these down with some certitude. If anyone is familiar with these coins and can help please tell me what you think. Thanks.
