Are these Communist Investigation report books worth anything?

[USERNAME IS VALID]

My father in law died a few years ago, he was on committees investigating communists in the 40's and 50's. I found these going through his belongings recently. There are about twenty of them. Any ideas how to market them if they are worth anything? SF, LA, Hollywood….I found some copies of the originals going on ebay for $35, these are originals.

Don't know what they're worth, but a lot of people sure had their lives turned topsy-turvy over that stuff back then!

I guess the first thing to do would be to get them authenticated. After that, maybe speak with an auction service that regularly deals with similar such papers/documents pertaining to history.
