Game Boy: $750 – $1,000
We spent hours on the Nintendo mobile game system, which was first released in the U.S. in 1989 until our cell phones became obsessed with us. These days, Game Boys go for hundreds in mint condition and, if you have a limited edition like Game Boy Light, over $1,000.

Original Transformers Action Figures: Prices Vary
The first line of these transforming robot action figures was released in 1984 by Hasbro. They may be worth even more than their original value if you were fortunate enough to keep the originals in their package: Optimus Prime figures are sold on eBay for upwards of $1,000 in flawless packaging, much more than their original sticker price.
