The coin sound originates from Nintendo's Super Mario Bros, released in 1985 for the NES, where collecting 100 coins earned an extra life. Its simple electronic chime became one of gaming's most copied reward cues as Mario games moved to later consoles. Clips of the sound spread through forums, ringtones and early video edits, and it stayed in use because even people who never played can read it instantly as money earned or a level up moment in a joke or stream.
