Large Copper Coin Found in Turkey ~60 Years Ago

Diameter is ~42mm, rim thickness is ~2.5mm, weight is 19.1 grams; it is slightly domed, with the obverse convex. Both sides appear to be 'crazed' fairly deeply into the disc material, which shows copper plainly (though it may be a bronze of some sort).

This is one of 10 or so with the same provenance, all having been purchased onesie-twosie in Turkish markets an' shops near an unknown American Air Force installation by a USAF Officer in the early 1960's. This is the largest an' the most legible of them; the others are, mostly, apparently quite a bit older...but several are nearly illegible. They'll all be posted in this (Ancient) forum in 2 batches: 3 better coins, an' then 7 lesser coins, with individual close-ups of obverse an' reverse of each one, later in the week.

I will be deeply grateful for any identification possible, as well as your considered opinions about how best (if at all) to render those most obscured by uncrustation into identifiable coins...without violating the universal caveat against 'cleaning'. Thanks for lookin'!

Not saying this is it but it's as close as I could find.

 

Well Done, Randy...Thanks!
Close in many ways, but at minimum it puts a near-date on the one I've pictured; I'm grateful!

 

Different reverse, but you nailed the obverse and time period. 405-367 BC is quite crazily old, definitely a cool one for the records!

 

It is a modern replica

 

Agree, it is a modern cast fake.

 

Thank you, all...Good an' proper work!
