I sell any record I upgrade. I am not a "collector" who keeps 6 copies of the same title, I am a music enjoyer. Usually my previous copy is in great shape - I might replace it to get an audiophile reissue (or a special audiophile reissue in the absolute favorite category), although not that often. If I have any others that I don't like, even if recently purchased, I sell it at a loss immediately. I don't want to see it or think about it.
There is a very small group - maybe 3% that I may want to listen to at some point just in case, but they are not near the records in an organized rotation that continues to evolve based on the way they sit in my rack and cubbies.
There are only maybe 1% that will never be played and are worth nothing - the records store won't take them for free. They'd be good to melt down. I can always keep the extra jackets....They are fillers in spaces I can't get to that make others accessible due to door hinges.
