Very small. Pictured with a wheat cent for size. I tried looking up by date but didn't see anything this small. Thanks in advance guys(gals)!
Iran is were the coin is from . A few better photos would help us tell you more information about it.
I can't find a match for the reverse either. I thought these pics would be good enough for a proper ID.

Is the silver ring some kind of mounting? I have several silver coins myself that has this "ring". But I can't seem to find some kind of split mark or soldering on any of these rings.
