This Pop is a limited edition variant of the Freddy Funko Pop dressed as Superman, featuring a metallic paint job and unique design. The rarity of this Pop and the popularity of both the Funko brand and the Superman character contributed to its high value.
While the Freddy Funko Metallic Superman is the most expensive Pop ever sold, there are many other valuable and sought-after Pops in the Funko world. Other rare and valuable Pops include the Freddy Funko Glow-in-the-Dark Green Lantern, which sold for $2,000, and the Funko Pop Alex Delarge from the movie A Clockwork Orange, which sold for $1,218.
It's worth noting that the value of a Funko Pop can fluctuate over time, and the rarity of a Pop can depend on a variety of factors, such as the number of Pops produced, the popularity of the character, and the uniqueness of the design. However, the thrill of the hunt and the desire to complete a collection with rare and unique Pops will always drive collectors to seek out these valuable additions to their collections.
