#14: Kellogg’s 1966 Thunderbird Toys
The 1966 Thunderbird toys, offered by Sugar Smacks, were a hit during the Space Race era. Made of plastic, these bright-colored toys fascinated children with their various shapes, embodying the excitement of space exploration.
Owning all four spaceship models considerably increases their value, with each fetching around $30 on eBay. Despite their initial mass production and being dismissed as disposable, collectors who preserved these toys now find them worth over $100.
