It sounds like you’ve done quite a bit of work curating and categorizing, and that is a very good thing. There are people who collect and some, I have taken note of, collect pre-VHS 35mm, others search strictly for one particular genre, say school girls in uniforms and other may only want scenes with bloopers or unintentional things happening in the background while sex is going on down screen. Search and bit and you’ll find people searching for curated collections and some are actually spending money buying a custom collection like you have done. It sounds like you know what’s in your collection well enough, that if you had certain hard to get, or maybe an entire collection from a particular director, or even uneditied director’s cuts, you’d be able to make name your price, if you can deliver a download that would fulfill , a genre the buyer has been searching for, but has not had the time to collect it himself.
You’ve enjoyed amassing the collection I’m guessing you’ll have a great deal of fun selling all or parts of the collections to others. Have fun whatever you decide makes the best sense for you.
