Records from the likes of the Spice Girls and Blur are becoming prized by collectors, with some selling for hundreds of pounds.
Albums by the Spice Girls and the Now That's What I Call Music compilations are among the unlikely releases which are now prized by enthusiasts.
Record Collector magazine said discs by the likes of Keane, Blur and Abba are also selling for high prices – sometimes hundreds of pounds.
Enthusiasts often spend a fortune on rare acetate copies, music by cult performers or vinyl versions.
The magazine's biannual list of the UK's rarest records now highlights mainstream acts and run-of-the-mill albums or singles which can fetch a decent price.
They include releases such as the long-running Now That's What I Call Music albums, featuring various artists.
Number 35 in the series, which was released in 1997, can command £80, mainly because at the time of its release few people were buying vinyl copies and it is now scarce.
Conversely, a CD version of Now 4, which was released in 1984, is valued at £200, because at that time the CD was a novelty.
Also on the list is the Spice Girls' second album Spiceworld, with original vinyl copies fetching around £30 – mainly because the vast majority of sales were on CD.
