The Most Valuable Collectors' Items in History

137. Original Tamagotchi

Manufacturer: Bandai
Original Price: $18*
Worth Today: $2,250*

For just $18, you could buy a Tamagotchi in the late 1990s, but the price of these first-generation, first-edition Tamagotchis has increased since then. The original 1996 Tamagotchis, which were released in Japan, have already sold for more than US$ 2,000 on auctions on eBay and other auction sites.

The Tamagotchi was launched in the United States in 1997 and quickly became a big hit among children in the 1990s and early 2000s. More than 82 million Tamagotchis have been sold. These digital pets still come in the same egg shape, with three buttons, that they did decades ago. The creators of the Tamagotchi even won the Nobel Prize in 1997 for their unique invention.
