Hmmmm .... you COULD run into some potential TM-like issues here, as I'm sure you've considered. I mean they themselves won't be coming after you or anything ... but due to their notoriety and respective fame, other entities and estates could, IMHO. What's to be on the respective SITES will have much to do with this, as well.
I would venture $250 - $375+ for each domain for interested parties ... less in wholesale, IMHO.
Good Luck with these ".US" domains. Truly.
