To provide an inexpensive value medium processor compatible with a compact and existing value medium processor for processing a small IC coin and a coin.

A value medium processor includes: a common rolling path 116 connected to a slot 114 on which a IC coin and a coin roll; a coin characteristic detection device 118 arranged at the side portion of the common rolling path 116; an IC coin characteristic detection device 118 configured to detect IC coin rolling on the common rolling path 116; an inlet to a coin path and an inlet to an IC coin path arranged in parallel following the common rolling path 116, a medium sorting device 134 arranged at the upstream of each inlet; a communication device provided on the side of the IC coin path for communicating with the IC coin; and a controller for actuating the medium sorting device 134 based on information from the coin characteristic detection device 118 and information from the IC coin characteristic detection device 118, and for switching the common rolling path 116 to one of the IC coin path and the coin path.
