5 Milliarden Mark
10 Milliarden Mark

50 Milliarden Mark
100 Milliarden Mark

They are extremely rare banknotes, and very much doubt if many collectors  would have them in their collection, thus, having them to swap would be virtually impossible.

I know it's hard to find them, but where better to look than here? 😁

Have you tried looking on various auction sites. I liked on a banknote collectors website and only one collector has two of those you want, but some are not listed, which means no one has them

Yes, I browse various auctions from time to time. 

I stumbled upon one once auction on ebay, but unfortunately, it was at the very end and I didn't have time to bid. ☹️

I'm looking for banknotes because they come from the city where I live.

I love collecting German Notgeld banknotes too. Added some a couple of days ago and now have 2,505 of them.

I also like the coins, but they are very difficult to get in the UK. As with both coins and banknotes, most of mine have come via exchanges.

wow, You have a large collection of notgelds :)

The banknote website I visit regularly has over 46,800 listed, most of which, does not seem in anyone's collection, so I have around 5%.

The lower face value banknotes are very colourful, whereas the very high value banknotes just look like a normal banknote, but there are a few exceptions.

I knew there were a lot of these notgelds, but I didn't think it was that many 😳

You have four coins from Greiffenberg, which I have never seen, and I do not have any from your city, although I have 176 notgeld coins from many other cities.

They're generally hard to come by and aren't the cheapest. I'm still missing two variants of the coins, and one of them (a1 pfennig without a hole) was on sale last year for around 1,000 euros ;(
