Archaic Coin ? (Id: Lydia Electrum)

If it's gold, and that small, I was gonna say Fanham(India)...
but after looking at the upside down sailboat or rightside up wolf's head, and an almost counter stamp(gotta be small!)obverse(?) I dunno.

Maybe the distortion from the magnifier. And there are a huge variety(and I mean huge)of fanham's, but the design is rather un-fanham like. They usually have only a few discernible lines and dots.

I may be able to find some reference, but a country would really make that easier.

It looks like an archaic Greek coin to me. The very earliest coins from Lydia were electrum coins with this design, a lion's head on the obverse and an irregular punch-mark on the reverse; example on Wildwinds. 5mm is quite small, but many fractional coins were issued in this series that were small indeed.

Electrum is an alloy of silver and gold that occurred naturally in Lydia. If your coin is one of these, it should be a pale yellow-white in colour. I can't tell the colour of yours from the pic.

The primary measurement for these coins is weight, rather than diameter, because the diameter can vary quite a bit and many (like youts) are oval in shape. If you can get a weight in grams to 2 decimal places, that would help narrow down the identity.

If it definitely isn't electrum, there were several other Greek city-states in the Archaic period that issued silver coins of similar design; Knidos and Lindos are two I can spot just browsing through the catalogue, but tiny versions of these coins are much less commonly seen. If you know where it was found, that might help with the identification.
