Anything Significant With These German Deutsche Stamps?

Just aquired a bunch of international stamps. Here is a variety of German stamps. I really need to order a international stamp catalogue. Are there any stamps of significance here? Some of them are rolled up, sorry if they are difficult to see. I have to flatten them out. Any info would be greatly appreciated!

Another one..

As far as I can see, most of them are German Inflation stamps. They worth very little as unused, but a little more as genuinely used, some considerably more. But you can always tell your friends that you have a stamp worth 1 billion marks (pre-euro German currency), that is what the face value on 1 milliarde stamp is.

Thank you for the response. Some guy on ebay is trying to sell the 800 stamp same as the one I have above for 1200 dollars! I knew he was trying to rip off someone!

Well, according to my Scott catalog if your 800 thousand is over 500, then it is #267, worth $0.20 unused, but $1,250.00 used. Yours unused, so you have nothing to worry about. If it was used, than you will have a hard time proving it is genuine, postally used copy, and not a CTO, witch are plentiful and worth as much as unused copy. So, unless that guy have a certificate handy, he is trying to rip off someone.

Great info. Thanks! No certificate as I see on his.
