I agree that it is most likely that people are stamping these notes for the appeal on ebay, I buy and sell WWII and other currency. In my research, I have not been able to confirm (or deny) that the Nazi's or the party/government ever stamped currency. These stamps were most commonly used to stamp documents, things like official documents, passports and orders, etc. However, as I said, I cannot find any reason or proof (thus far) that currency was ever stamped. I will say, the stamps however being used "might" actually be authentic though. The original wooden stamps used are rare and can go for a pretty penny at auction or sale to collectors. I happen to have a set of wooden stamps that were used during this time - often these stamps, usually pressed on an ink pad and then slammed onto a document to make official or confirm receipt, or to cancel a document face (the stamp pad is typically metal and not as effective as a rubber stamp - so it requires quite a bit of force to make a good impression or it requires a soft surface behind the document or item to be stamped). I also have a few notes that are also stamped like this and I tend to agree that they are stamped to increase the perceived value of a note (such as on ebay) but in fact, if the note is in good shape, it is most likely, the stamp merely decreases the actual collector value of the item - but as you said, out of curiosity and for whatever appeal it might have for a potential buyer, it can been seen on ebay, people are buying them and often they are paying more for stamped notes - even though it realistically defaces the historical value of it.
