I have this coin, which I've no idea if it is a counterfeit or not. It's suppose to be made out of silver or so. I've got no scanner so I can only give a description. It's bigger than the US 50 cent, one side it has brittania standing up holding a trident with a date 1898, while on the other side it has chinese and (I believe) Mughal characters. Is it worth anything? Thanks!
