Maker: King-Seeley Thermos
Approximate Value: $5,201.91
Just when you realize these are all based on super popular television shows or pop culture icons, you come across this one. “Man From Atlantis” was a short-lived television phenomenon in 1977-78. Four made-for-TV movies led to a series, but the series only lasted one, 13-episode season.
Meanwhile, King-Seeley Thermos made these cool lunch boxes. They halted production faster than you can say “mermaids are real,” and there may only be three of these bad boys left. In 2013 someone put down a cool $5,201.91 on eBay to own one of them.
