The invention relates to a roller-type coin screening machine which comprises a supporting frame, a power source, a coaxial roller screening mechanism, a material feeding end and material discharging ends, wherein the coaxial roller screening mechanism is fixed at both ends of the supporting frame and are driven by the power source to make coins with different face values enter the machine together from the material feeding end; after being screened, the coins are respectively discharged from the material discharging ends; the coaxial roller screening mechanism adopts an outer roller and an inner roller for coaxial positioning; due to through holes with different diameters in the surfaces of the outer roller and the inner roller, the coins with different face values can be screened and can reach different material discharging ends through different outlets in a collection device. The roller-type coin screening machine is reasonable in design and is concentrically fixed and sleeved through the two rollers with identical tapers and different diameters; when the rollers rotate, centrifugal force generated may improve the coin sorting efficiency, so that the aim that a large number of different coins can be classified and screened is accurately fulfilled.
