Vinyl is worth a fortune these days. It's not going to drop, it's been going up and up for years. These are the values of some of my records, based on recorded sales on Discogs Marketplace alone:
Blur - Good Song 7" (Banksy sleeve) - Median sale value £292.12 Maximum sale value £460.75
Nirvana - In Utero (clear vinyl) - Median £203.84 Max £364.76
Nine Inch Nails - The Downward Spiral - Median £120.69 Max £324.66
Oasis - What's the Story (Gatefold) Med £152.41 Max £317.28
Oasis - Definitely Maybe (Gatefold) - Med £169.52 Max £281.20
Ride - Going Blank Again - Med £60.01 Max £246.75
My Bloody Valentine - Loveless Med £141.29 Max £243.59
And it just goes on like that. It's mind-boggling tbh. So yeah, make sure those records are stored properly
