I have almost every manual and module from the glory days of AD&D and what good would it be to have the books without the dice? I have one pristine set of crystal dice that aren't with the bigger collection you see here but those are AWOL at the moment.
I still have most of the original set of 6 I bought back in '78 or so. (You can tell from the worn edges on some of them.)
My dad has a 'treasure box' of trinkets and toys he collected from gumball machines and Cracker Jack boxes when he was a wee lad. This would be my version of that collection.
