A coin accepting apparatus. The apparatus includes a pair of generally parallel, spaced-apart plates. The plates define a coin track for receiving and guiding coins wherein each plate has a side facing the coin track and an opposing side facing away from the coin track. The apparatus further includes a sensor on the opposing side of one plate for detecting a characteristic of coins to be validated and first and second retainers on the opposing side of the plate for inhibiting movement of the sensor. The first retainer includes a spring arm for engaging the sensor and biasing the sensor against the opposing side of the plate. The second retainer engages the sensor and constrains movement of the sensor along an axis generally perpendicular to the opposing side of the plate.
