The coin sound first appeared in Super Mario Bros., released by Nintendo for the Nintendo Entertainment System in 1985, where it played every time Mario collected a coin in a level. As Mario became Nintendo's most famous character, the chime travelled with him into sequels, spin-offs and handheld games, becoming one of the most recognised sounds in gaming. It later spread beyond games into online videos, memes and streams, where its short, positive tone still works as a universal signal for earning something.
