General question for ya. Ran into someone who has some WWI period German paper currency he wants to sell. Nothing in fantastic condition, but not falling to pieces either. My question isn't so much about the condition (since I don't have pics yet), my question is how collectible is this type of money? If I bought it I'm probably not going to keep it because I have little interest, but basically I don't want to buy it and not be able to re-sell it because no one collects it. From what I can tell, the currency is marked from 1917 to late 1920's. If I can get some pics I will post them. Any help would be appreciated. Thanks!
