10. Teenage Mutant Ninja Turtles

The Teenage Mutant Ninja Turtles (TMNT) is another pop culture phenomenon that has left a lasting impact since its introduction in the late 1980s.

Vintage TMNT toys, particularly those from the original Playmates line in the late 1980s and early 1990s, have become valuable collectibles.

For instance, on eBay, the 1993 Teenage Mutant Ninja Turtles Scratch Prototype First Shot is currently listed at $100,000.00. TMNT offers a wide variety of toys and memorabilia, many of which are worth significantly more than their original prices. 

A signed sketch of the characters, created by the creators Peter Laird and Kevin Eastman, is being sold at $79,550.00.
