A coin-sending device wherein coins can be lined up and discriminated at the same place, limitation of inner spaces of game machines or the like in which the coin-sending device is incorporated can be mitigated, and enlargement and complexity of their structures can be prevented, the coin-sending device comprising a coin-selection part 4 on a forcible-transfer passage 20 where a transfer force of a rotary disc 3 acts on coins sent from the rotary disc, coins are sent sequentially one by one to a second-side passage 2 following drive of the rotary disc 3, false coins IM at the coin-selection part 4 are removed through a removal opening 40 and only true coins are picked up at the coin-selection part 4, whereby coins are lined up and discriminated at the same place where the rotary disc 3 is provided, so that difference of height between an inlet of lump-insertion for coins and an outlet 202 of coins after discriminated can be made smaller, limitation of inner spaces of game machines or the like for mounting the coin-sending device can be mitigated without enlargement and complexity of the structures.
