Coins were made with holes for several reasons, two of them being to save on the amount of metal used to make the coin, and to have a way to string all of your coins together for easier handling.
The country of origin and the denomination of the coin would be a big help. Holes in the centre of coins is no longer as widespread a practice as it once was, although some countries continue to do so as a tradition.
