As everyone has said, I believe its size and weight. A few years ago when I was in Canada, I found that a British 2p coin works in some $1 machines - Won lots of teddies for less than £1 ; )

Checks diameter & thickness . The coins also pass a magnet which produces Eddy currents this can then determine the material that the coin is made from.

Size and weight.
Now here's a cool trick.
One Swaziland Lilangeni coin is EXACTLY the same size and weight as a British one pound coin.
One Lilangeni is worth GBP £0.07
go figure.
(the plural of Lilangeni is Elangeni, the international symbol for the Elangeni is SZL)
