Good Afternoon Ladies and Gentlemen

I'm stupid, and I've done it again: purchasing collectables that I know nothing about. This time, Slot Cards and Room Keys
So a few quick contact sheet scans of my new toys. Many/most will be , once I get a clue if they are worth a dime or a dollar, and figure out which ones I want to keep. Overall there are over 1000 cards and most of them are at least slightly different.
Any comments, help, pointers, offers, etc. muchly appreciated.
