<- That one fits best. I guess Greek because there's no legend...but the weight...maybe some kind of shield or solar wheel on the reverse.
Well, it's got to be an 'Eastern' coin, if you have it A-noob LOL Hmmmm, the first 'Indian' deity who invented the wheel????
Too thin for Greek, no legends so not Roman. The thinness of the flan suggests medieval. No Islamic writing so suggests its pre-Islamic or European or other areas not conquered by Islam. Given this, my guess would be northern European or South Asian, but that is all I got.
