You can ask, but that doesn't mean someone can answer.
I like Richard Plant's book, "
Greek Coins and their Identification" or something like that. Some people put him down because he uses woodblock prints, and they can't die match their coins that way. But one thing he has is an
index of images, and listing by images. So if you have a coin with a crab on it and
Heracles, one can look up crabs (better than trying to
search through
Heracles), and figure out that it may be
Kos.
But that might be something that might solve you problem, a reference with an
index of types, so you can look it up by type and scan the images. I am not saying
Plant will solve your problem, but
Plant is for both Greek and
Greek imperial. You don't have inscriptions, so you can't look it up that way.
I've got two small AE coins each with a
head (male) on the
obverse, and a tripod on the
reverse. Have no idea where they came from, just too many heads and tripods out there. Look at it this way, maybe you have something so
rare that no one else has heard about it!
