Those are a nice find! Do not fold them or write on them! If you can, visit a local coin dealer and get
some nice, PVC-free currency holders to store the notes in.
There were about 1.3 million of these '85 "D" star notes made and at one time they had a book value of around 4X face value. The ones you have appear to be very nice. I'd venture to guess that you probably have the most intact consecutive serial numbered ones of them still around!
The problem selling them all at once is it is a lot of money to tie up by a dealer or collector. (There are a not a lot of 100$ bill collectors to begin with.)
Most, (not all!), local coin dealers would not offer much over face value for them.
In my opinion, you'd be better off trying to market them individually or in pairs on one of the mainstream auction sites. The object of the game, if you are trying to sell them, is to get them in front of as many potential buyers as you can without overloading the market and driving the price down. (ie...don't list them all at once!)
Hope that helps!
