Sometimes you don't know what you've got 'til it's gone—and if you've thrown out milk crates full of vinyl records that included one of these collectibles, brace yourself for serious remorse.
According to , the top three records with the highest resale value are, in order, Bob Dylan's The Freewheelin' Bob Dylan (1963), The Beatles' White Album (1968) and David Bowie's Diamond Dogs (1974). Each is worth tens of thousands of dollars, if they're in the right condition, of course.
For example, a rare, mint condition copy of Dylan's second album for $35,000. Its value comes from a mistake at the pressing plant. Last-minute changes to the album resulted in the plant producing a limited (yet unknown) number of copies with older versions of four songs. (This explains what to look for if you think you've got one of those goldmine records on your hands.)
The first copies of The Beatles' self-titled album (later named the White Album) were given to record executives and have special serial numbers on them. The first-ever copy sold a few years ago, also for $35,000. David Bowie's Diamond Dogs gained notoriety because of a mistake, too: Earlier versions of the album featured what some considered obscene animal nudity on the cover art, which the record label had airbrushed out in later versions. Original copies fetched $3,550 on eBay in 2013. The price for one now, following Bowie's death, is likely to have doubled or tripled.
