Seems you're having some bad luck, Maria... Hopefully you or someone you know didn't spend any (real) money on them.
Great question, unfortunately they're not worth a whole, if anything at all. Contemporary counterfeits however are very collectible and worth some money, these are pieces that were crafted during the coin series time in commerce.
Thus far things are not looking positive, but better safe than sorry. Feel free to post photos of the others just in case.
