1. it should have sentimental value for you. but many countries have switched to the euro and I don't know about Greece or Poland's money.
2. haha,of course they do u can collect them for a collection or maybe someone else like them,such as me, will buy them good luck
3. Of course they have value. Take them to an expert, there are thousands of people that collect this things and pay good money for them. Its like saying, I have this original Luke Skywalker doll from the 70`s does it have value???
