Here is a picture front and back of a gold coin that I am interested in buying, however, I can not seem to verify if it's an actual coin. The owner says that this is a King Mir Zakah coin, but I have my doubts and believe him to be wrong. It is 2.14 grams os solid gold as far as I can tell, however I haven't conducted testing for that yet. Can anyone help me identify this coin and maybe an idea of its worth.
