This clip comes from the notification sound used for incoming money on WebMoney, the online payment system, where a falling coin signalled a payment had arrived. The recording is credited in its file data to Bruni AFX, and its simple coin-on-table effect made it easy to recognise even outside the payment app. As short notification sounds moved onto soundboards and video editors, creators began reusing it as a shorthand for cash, sales and sudden wealth. It remains popular because the meaning is immediate: one coin drop tells the audience money has changed hands, without any words or explanation needed.
