PURPOSE: To miniaturize a coin selecting device and to attain sure selection of coins by inscribing coins to a carrying circle by centrifugal force and selecting the coins in the ascending order of their diameters.

CONSTITUTION: A coin thrown into a hopper 1 is fetched into a delivering hole 3 of a delivering disk 4 rotated by a driving machine 2 and carried, fetched into the fetching hole 11 of a fetching disk 12 rotated synchronously with the disk 4 in the reverse direction, and carried on a carrying plate 14 while being inscribed to the outer periphery of the hole 11. Selection holes 13a to 13f inscribed to the carrying circles 15 with the same diameter as the outer peripheries of the holes 11 and having diameters slightly larger than that of their corresponding coins are arrayed on the carrying disk 14 in the ascending order of coin diameters. The coin carried into the hole 11 while being inscribed to the carrying circle 15 is dropped from the corresponding holes 13a to 13f and stored in its corresponding case 16.
