A coin handling apparatus comprising: a transport path having a transport surface provided with an opening portion through which a coin is dropped; a transport unit including a transport pin, wherein the transport unit is configured to transport a coin on the transport surface along the transport path from upstream to downstream in a transport direction by pushing the coin with the transport pin; a gate for opening and closing the opening portion of the transport surface, wherein the gate is configured to move between a first position in which the opening portion is closed by the gate and the coin transported by the transport unit is not dropped through the opening portion, and a second position in which the opening portion is opened by the gate and the coin is dropped through the opening portion; and a driving unit configured to control the gate to move between the first position and the second position, wherein the gate includes a first member disposed upstream in the transport direction and a second member disposed downstream in the transport direction, the first member is configured to rotate in a first direction when the gate moves from the first position to the second position, and the second member is configured to rotate in a second direction opposite to the first direction when the gate moves from the first position to the second position, upper surfaces of the first and second members (11,12) form a flat surface being substantially flush with the transport surface of the transport path when the gate is in the first position, and the driving unit is configured to drive the first and sec ond members (11,12) to move the gate between the first position an d the second position characterized in that the coin handling apparatus further comprising: a link structure configured to connect the first member and the second member such that movement of the first member and the second member is synchronized in a case that the gate opens and closes the opening portion of the transport surface, wherein the second member has a shape including an opening in an area where the transport pin passes when the gate is in the second position, and the first member has a shape that coincides with the opening of the second member and prevents the coin from dropping into the opening in a case that the gate is in the first position. a transport path having a transport surface provided with an opening portion through which a coin is dropped;
