The coin chime comes from Nintendo's Super Mario series, where it has played whenever Mario collects a coin since the early platform games. Its bright, instantly recognisable two-note pattern made it one of gaming's most familiar audio cues, and it travelled far beyond the games through gameplay clips, streams, memes and edits. Today creators reuse it as shorthand for earning, winning or getting paid, because almost anyone who has played or watched Mario recognises the reward it represents.
