A coin sorting device is disclosed having a coin sorting passage defined between a stationary side plate and a movable side plate openably connected at the upper side thereof to and spaced sidewardly from the stationary side plate, the coin sorting passage is provided with a track movable sidewardly to open the passage downwardly. There is at least one set of coin material detector coils including transmitting and receiving coils positioned in alignment with each other at the opposite sides of the coin sorting passage, respectively for detecting a load impedance of a coin running on the track. Both of the transmitting coils and the receiving coils are opposedly fixed in a stationary retainer fixed in predetermined position relative to the track. This track is adapted for retracting out of the coin sorting passage sidewardly to open the passage downwardly and is positioned in the predetermined position in the passage by a positioning device.
