You knew that vinyl was going to make an appearance somewhere on this list - we wouldn't have mentioned it at the start if it wasn't! The vinyl revival has been one of the most surprising trends in the music world of the past couple of decades, with vinyl becoming responsible for an increasingly large share of the physical record sales market. One of the most valuable individual records you might own comes from 'The Boss' himself, Bruce Springsteen.
'Spirit in the Night' was one of the very first single releases that Springsteen released after he signed with Columbia Records; i.e., before he really made it big. If you were onto Springsteen before anyone else, you could now make a nice profit from it. The original seven-inch version of the single is worth up to $5,000 if it's in good condition and still has its sleeve.
