With some rare titles I’ll buy a trashed copy out of a pound bin to get a good cover or inner. I’m sufficiently obsessive to rebuild stuff correctly, i.e. exactly right cover for that issue etc. I have many albums I’ve assembled a copy out of multiple copies, I’ve certainly posted about my EX to NM 1st press of Electric Warrior; that was four copies, one for the record, the cover, the inner and the poster. It didn’t actually cost much to do as I did it over 20 years ago, I think I paid £15 for the record, no more than a fiver for any other part, and it’s a £400-500 album now! Plenty more I’ve built in a similar way. I do actually have a stash of covers and printed inners as when anything badly damaged/scratched comes in with a collection I’ll asset strip it in case that can help build a better copy later. It means I can then buy a good copy with sticker damage, writing or whatever and just bin the bad sleeve.
