A Famicom cartridge of Kinnikuman Muscle Tag Match: Championship Commemorative Gold Edition has sold for US$10,023 in an online auction.

The "Gold" edition of Kinnikuman Muscle Tag Match (M.U.S.C.L.E. in the West) is exceedingly rare — only eight copies of it exist.

During the mid-1980s, they were given out as prizes for a Kinnikuman Muscle Tag Match tournament that was held in eight locations across Japan.

Kinnikuman Muscle Tag Match is considered one of the worst games of the Famicom/NES era.
