The coin sound first appeared in Super Mario Bros. on the Nintendo Entertainment System in 1985, composed as part of the game's iconic 8-bit audio by Koji Kondo. Every time Mario or Luigi collected a coin, the same two-note chime played, and collecting 100 coins earned an extra life. The effect carried through later Mario games on new consoles with cleaner samples but the same melody. Its constant reuse in gameplay videos, remixes and memes has made it one of the most recognised reward sounds in gaming history.
