Herein disclosed is an incorrectness detecting device for detecting the coin piling condition in a piling cylinder of a coin packaging machine. The detecting device includes a sensor which is made coactive with a coin kind selecting dial so that its height may be varied in accordance with the height corresponding to a preset number of coins piled. Further inclusive is a detecting element which is to be brought downwardly into contact with the upper side of the uppermost one of the piled coins, when the preset number of coins are piled in the piling cylinder, so that an electric circuit may be made through the piled coins. Further inclusive is a sensor element which is made coactive with the detecting element while corresponding to the sensor. As a result, the coil piling condition can be detected in response to both the signals, which are generated by the interaction between the sensor and its element, and the signals which are generated by the electric circuit made through the coins.
