The undisputed holy grail and hardest Funko Pop to acquire is widely considered to be the Willy Wonka & Oompa Loompa Golden Ticket 2-Pack, of which only ten sets were ever manufactured and distributed through golden tickets hidden in chocolate bars at a 2016 convention event. Other legendary, nearly impossible-to-find pieces include the Glow-in-the-Dark Clockwork Orange Chase and ultra-limited Freddy Funko variants, which command tens of thousands of dollars on the elite collector market.
