I think it is an Obol. The flip didn't have any information. I was just excited to get it under the lens. An Owl has been on my list for years. I still wish to get a Tet or something larger. This one will have to do for a while. Athens, Greece 480-400 BC .6g, 9.5mm Is that a counterstamp of some sort?
The flip says Attica, forgot that. I just looked thru wildwinds, I couldn't find a match. Is there a better place to search?
is it a bit like this one? https://www.acsearch.info/search.html?id=4107570 It looks like the coin has a hole that was filled - on the helmet and one leg of the owl.
