My hobby is to collect old antiques, especially coins. I gave an advertisement that I would pay 1 Lakh if any one gives me King XYZ period coins which I was looking badly. One day a person came to me and showed his collections. Infact he had King XYZ period coins also. I was very happy and analyzed the coin. It had the emblem of the king in the front side and when I fliped it and saw the other side it said King XYZ, the great - 5 B.C.
I got irritated and asked him to go. How did I find that the coins are fake?
