The invention relates to a testing device 10, that can be a component of a feeding device to feed coin blanks 11 to a coining press or a minting station 12. The testing device 10 has a contactless measuring first sensor device 30 and/or a second sensor device 40. Every sensor device 30, 40 that is present controls an associated removal device 32 or 41. Each sensor device 30, 40 detects a certain property of the coin blank and compares it with a corresponding standard specification. If an unacceptable deviation from the specification is detected, the sensor device 30, 40 in question controls the respective associated removal device 32, 41 to discharge the coin blank from a main conveyor device 13 which transports the coin blanks from a feeding end 14 to an exit end 15.

An apparatus for discrimination and conveyance of coins achieves downsizing of this apparatus itself with a simple and low-cost structure compared with conventional ones. The apparatus includes a coin separation unit, a coin discrimination unit, and a coin conveyance and distribution unit. Coins separated in the coin separation unit are moved in a first direction through a first delivering region and delivered to the coin discrimination unit. The coins whose denomination and authenticity are discriminated in the coin discrimination unit are moved in a second direction approximately perpendicular to the first direction in a plan view through a second delivering region and delivered to the coin conveyance and distribution unit. In the second delivering region, a conveying direction of the coins is changed from the first direction to the second direction. The coins are distributed while being conveyed in the second direction in the coin conveyance and distribution unit.

A coin processing system comprises a rotatable disc including a resilient pad coupled thereto for imparting motion to the plurality of coins, the resilient pad including an outer peripheral edge, and a stationary sorting head. The stationary sorting head includes a lower surface forming a coin path for directing movement of each of the coins, a stripping area of the coin path including at least one stripping surface operable to retain at least one coin when overlapping another coin such that the other coin is separated from the at least one coin by the motion imparted by the rotatable disc, and a queuing area of the coin path that receives the plurality of coins from the stripping area, the queuing area including a beveled surface curving substantially parallel with the outer peripheral edge of the resilient pad to guide the coins in a single file configuration to a discrimination area.
