The problem is, it's a base metal, the layer of gold plating is so thin it has no bullion value (the value of the actual gold).
And the other problem is, it's a token not a coin and not so many people collect these kind of tokens , so not much collector's value either. Price is often a question af supply and demand. In this case there will be little demand, so a low price. But I'm sorry I have no idea what that price is.
According to the page and the mintmark it seems to be at least an official item from the state mint and somebody who collects such things would maybe give you a few bucks for it ... if it was me you would have to pay me to take this off of you.
--> Value: - X (currency) to X times a few (currency)
