There are lots of "price guides" out there, but the truth is, the value of stuff like this is really what someone would pay for it, not what a price guide says it's worth. The other issue is the definition of "good" which is pretty exacting with collectible paper money.
Anyway, eBay, because they're so huge, is my favorite source for getting an idea what stuff is worth:
In short, not much... probably not more than $3-$4.
See the prices on some of these:
