Let's calm things down a little. We understand that as much as you may want one, you probably don't have an old guitar belonging to John Lennon at home. That's fine; just remember that any old guitar is still worth money. We're going to take a breath and go back to more common items that you'd never dream were worth money. Hands up if you remember Pogs?
If you weren't there at the time, Pogs were a brief fad which involved cardboard discs, which could be flipped and traded between friends who would play a game that involved hitting them with a larger disc. At one stage during the 1990s they were in every playground in the country. If you still own the full 'Marilyn Monroe' set, it's worth more than $1,000. If you collected the 'Jurassic Park' set and have the holographic versions of each of the dinosaurs, you can add several more zeroes to that. The set is worth more than $1m!
