Is this real?

I come across this somewhere in my travels. It does have silver content. I had a jeweler test it for me. It is just smaller than a dime round. and about as thick as 3 dimes (US 10 cent) wide. The obverse extendes well above the rim, and the reverse is in-set, giving the coin a dome shape when placed on a flat surface with the obverse up. Sorry, I don't have my measuring equipment with me.

 I read that at one time these were reproduced for sell to tourest. Does anyone know anything about these?

I can't find it listed on the web site. The tetradrachm that looks like it, is to big.

Here are the measurements of the one I have:

14.1mm Dia. (Average of 4 measurement)
4mm thick


I wrote the weight down as 3.95g when I was measuring, but I believe this was an error. I will check and add a weight shortly

Athens, Attica, 479-393 BC, Silver drachm.

Do you have any better pictures?

I can take a better picture. That picture was a quick shot.

This design was used on for more than one coin? Is it listed already?
