I get this from Tehran, the weight is 28.73g, and same size, you can find my pic is the same as this real one(internal tooth at 9 o'clock;and two points,one on the right of the year,the other is at 7 o'clock,but the gold looks too new.....
I have seen people cleaning a coin with a steel brush. Perhaps tha is what happened with this coin?
Copies of rare coins are often made by making a mold of an real coin.
