You might want to troll eBay for suspiciously familiar albums or collections recently put up for sale. If the crooks know what they got -- and they probably do, having come back to take the vinyl -- they may attempt to find a collector or other high-powered buyer themselves rather than try to fence the discs to someone who hasn't a clue what they're worth.
