Mark... you need to make a museum for your 45s when you're an old guy, they seriously need to be saved for future generations to marvel at and also future prosperity, your life's passion is pictured right here in this forum, its not just images of killer 45s, it also shows the absolute commitment and love for the genre which you've spent a good part of your life involved it, its more than just the records, its the man too.
It would be such a shame in my opinion for these 45s to end up in the hands of people who really don't deserve them in the future, folks who haven't "lived" it just cos they have the moolah, I'd personally rather see all these 45s go to a museum or at least sold only to "known" individuals who are garage freaks to the core of their soul.
In which case, I call dibs on The Tremors : )
Either the museum option will be great OR please promise me you'll have these cremated with you when you go.... so they literally go back to the grave so to speak.
