Welcome to the forum. We really need more information before we can give you much help. Can you post a picture of the coin? If not, just spell out the letters on each side of the coin. If they are so worn that you can't tell what they are, the condition of the coin is too poor to have any numismatic value.
16 years this poor guy has been sitting in his village waiting for an answer, and that's the best you can come up with? The least you could have done is to send him a camera so he can take some photos.
i'm having a funny image of an old man with a coin somewhere in the junk box finally, after 16 years, having an epiphany
