The audio titled "Coin Storage" kicks off with the soft jingling of coins, underlining the theme of a bank. As the audio progresses, the rhythmic tinkling of a bell is introduced, suggesting a busy bank atmosphere where transactions happen continuously. Intriguingly, the intermittent sound of a crank being turned can be heard, symbolizing the manual operation of a traditional coin storage system. The entire audio description creates a vivid image of an old-fashioned bank, with its coin storage, a bell signaling each transaction, and a hand-cranked machine used for handling the coins.
