Furby

Not too many people liked how the Furby looked. If you’re one of those and kept their original Furby in the box, it may be time to thank your lucky stars because the more rare they are, the more expensive they become. In fact, one even sold theirs for a whopping $700. Not bad for a toy that was deemed to be very ugly by a lot of people.

Aladdin’s Black Diamond

Aladdin’s Black Diamond VHS version sold for no more than $17 at Toys-R-Us. Now, it costs a lot more to get a copy of this short Disney movie. In fact, reasonable sellers can give you a copy for $80 while the more cunning ones are asking for as much as $1,000. Needless to say, its value has increased by more than 300 percent.
