Welcome to Numista. I cant find anything for the 2004 date here on Numista but the Numista catalog is a work in progress especially for Tokens (exonumia) such as this example and it is not a Coin per se. Here are 2 we do have cataloged and they are are both Brass. So the example is probably brass. The only way to be certain of the difference between brass and gold would be to weigh them. Not convinced any of these types were made of gold in the first place.
