The invention relates to a coin sorting machine. The coin sorting machine comprises a sorting device (1), a temporary storage device (2) and a storage device (3) which are arranged in sequence on a frame (6) from top to bottom, wherein the sorting device (1) is used for sorting coins of different currency values; the temporary storage device (2) is for sorted coins of each face value to wait for confirmation of the currency values; the storage device (3) is used for storing each coin of a confirmed currency value; the sorting device (1) comprises a sorting disk (11), an elastic rotating disk (2) arranged on the lower side of the sorting disk (11), and a transmission mechanism (13) for driving the elastic rotating disk (12) to rotate relative to the sorting disk (11); the sorting device (1) is used for storing coins of different currency values through rotation of the elastic rotating disk (12) relative to the sorting disk (11) and a corresponding notch and a coin outlet in the sorting disk; the sorted coins enter the temporary storage device (1) to wait for confirmation by each customer in order to be returned and stored. By adopting the coin sorting machine, possible contradiction generated by the difference between a value estimated by the customer and a value counted in a bank can be greatly reduced.
