So a few times I've gotten lots of low grade common ancients from a very reputable dealer. I know they're real and have identified many of them with just Google lens and comparing to the results shown. Some of them are just not coming up with anything similar or Google lens just shows me completely different looking coins. Most resources I find seem to not be beginner friendly so I'm looking for something that might help that.
I remember seeing a site recommendation awhile back that would essentially let you filter out coins by picking out what was on the reverse; castle, person, multiple people, chariot, animal, etc. For the life of me I can't find it again though.
Any help on finding that site or maybe another that would help me learn to identify them myself?
