The invention discloses a coin sorting device. The coin sorting device comprises a housing, wherein the upper end of the housing is provided with a coin inlet; a coin storage chamber which is arranged in the housing in an inclined manner; a rotary disk, wherein the rotary disk is arranged on the bottom part of the coin storage chamber in a rotary manner, a plurality of coin storage cavities are formed in the rotary disk in a concave manner, the highest part on the bottom part of the coin storage chamber is provided with a coin discharge port corresponding to the coin storage cavities, and the coin discharge port is provided with a coin discharge switch; a rotation mechanism which is used for driving the rotary disk to rotate; a sorting channel, wherein the sorting channel is arranged in the housing and spirally extends downwards, an upper inlet of the sorting channel is corresponding to the coin discharge port, and three coin outlets are formed in the external side wall of the sorting channel; and package cylinders, wherein one package cylinder is arranged below each coin outlet. According to the invention, coins slide downwards in the sorting channels, and centrifugal forces are generated, so that the coins different in size are enabled to be discharged from the three different coin outlets, automatic sorting is realized, and the sorting is accurate and high in efficiency.
