A coin selecting apparatus includes a damper ball arranged beside a coin passage to contact inserted coins and a ball guide for smoothly guiding the damper ball, in order to adjust inserting speed of the inserted coins in association with movements of the damper ball. The damper ball travels from a first position to a second position of the ball guide upon impact of the inserted coin to absorb kinetic energy of the coin, thereby regulating the speed of the coin. The damper ball then returns to the first position as rolling and contacting with walls of the guide, thereby changing the location of the impact point on the damper ball so as to prevent the ball from being worn or impaired. Where the first position is placed at a lower position than the second position, the damper ball can return by itself in aid of force of gravity. A pushing member, if provided, may enhance applicability of the coin selecting apparatus since the ball guide could be designed less restrictedly.
