A copy of the Norwegian electronic duo Röyksopp's album 'Melody A.M.' has sold on Discogs for an astounding $6962.

So what is it that makes this particular record worth so much? Back in 2002, the group sent famous street artist Banksy 100 copies of an ultra-limited white label pressing of the album so he could add his personal touch to the double-LP.

The anonymous artist created a custom stencil design that he then used to spraypaint each cover. There are still four copies of the rare record available on Discogs, some going for as much as $12,000.
