"Super Treasure Hunt" (STH or $TH) serves as the collector's moniker for the exclusive "Super Secret Treasure Hunts," introduced in 2007 with distinctive features such as Spectraflame paint, rubber wheels, and the notable "TREA$URE HUNT$" label, indicating their special status within the mainline; since 2012, Super Treasure Hunts have maintained their clandestine appeal by being discreetly placed among mainline releases, identified through a specific logo system, while the enduring golden Treasure Hunt flame logo on their card backs, introduced in 2013, has solidified their coveted status in the realm of Hot Wheels collecting.
