The coin sound comes from Nintendo's Super Mario Bros., first released in 1985, where collecting a coin triggered a bright two-note chime and added to the player's score. As Mario games spread to new consoles and generations, the sound became shorthand for picking up treasure, even outside the games themselves. It later moved into YouTube edits, livestreams and meme videos, where creators reuse it to signal money, success or a reward. Its short length and instant recognition keep it useful decades after its debut.
