I have a collection of about 3000 post-1980s cards that I kept in a binder with sheets, so I could flip through and admire them. After 15+ years, I found many of the cards sticking to the plastic and risking damage.

Is there a preferred method for long-term storage? Should I use penny-sleeves for every card and store he cards in containers that hold 500 cards (abandoning the binders). Curious what everyone else does for your collections.
