i just want to know how much money they are worth
However much someone is willing to pay. Technically, $5.95, or however much you bought them for. Of course, they are probably worth more to someone given their somewhat rarity (and subsequent versions having been released). But, we are in no position to place a definite value on them. You may find some people willing to pay $5 for them, and some other person willing to pay $50. As well, it depends on how much others are selling them for on ebay and through other means. The market fluctuates based on a number of such variables, and others I haven't mentioned (i.e., how the economy is doing--tighter lending, economic downturn = stricter spending budget for things like cards, thus willing to pay less; again, this only applies to some, as there are others who still have money to burn, weren't effected by the economy, etc).
In sum, they're worth however much you can get for them.
