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. ## Claims ### Claim 1 A coin processing system for processing a plurality of coins of a mixed plurality of denominations having a plurality of diameters, comprising: a rotatable disc including a resilient pad coupled thereto for imparting motion to the plurality of coins, the resilient pad being generally circular and including an outer peripheral edge; and a stationary sorting head including: a lower surface generally parallel to and spaced a distance from the resilient pad, the lower surface forming a coin path for directing movement of each of the plurality of 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 tangentially with the outer peripheral edge of the resilient pad to guide the coins in a single file configuration to a discrimination area. ### Claim 2 (depends on 1) The coin processing system of claim 1, wherein: the stripping area includes a first stripping ramp located at an initial edge of the stripping area and structured with an angle from the lower surface in a first direction that is tangential to a rotation of the rotatable disc. ### Claim 3 (depends on 2) The coin processing system of claim 2, wherein the angle of the first stripping ramp increases in a second direction that is a radial direction of the rotatable disc. ### Claim 4 (depends on 3) The coin processing system of claim 3, wherein an increase in the angle of the first stripping ramp is constant across the stripping area in the second direction. ### Claim 5 (depends on 3) The coin processing system of claim 3, further comprising a second stripping ramp located in the second direction, towards a center of the rotatable disc, from the first stripping ramp. ### Claim 6 (depends on 5) The coin processing system of claim 5, wherein the second stripping ramp is located in a counterclockwise direction in the first direction. ### Claim 7 (depends on 5) The coin processing system of claim 5, wherein an angle of the second stripping ramp increases in the second direction. ### Claim 8 (depends on 7) The coin processing system of claim 7, wherein an increase in the angle of the second stripping ramp is less than the increase of the angle of the first stripping ramp. ### Claim 9 (depends on 5) The coin processing system of claim 5, wherein the angle of the second stripping ramp is constant across the stripping area in the second direction. ### Claim 10 (depends on 9) The coin processing system of claim 9, wherein the angle of the second stripping ramp is different from the angle of the first stripping ramp. ### Claim 11 A stationary sorting head for processing a plurality of coins of a mixed plurality of denominations having a plurality of diameters, comprising: a lower surface generally parallel to and spaced a distance from a resilient pad of a rotatable disc, the lower surface forming a coin path for directing movement of each of a plurality of coins, the resilient pad being generally circular and including an outer peripheral edge, and 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 motion imparted by the rotatable disc. ### Claim 12 (depends on 11) The stationary sorting head of claim 11, wherein: the stripping area includes a first stripping ramp located at an initial edge of the stripping area and structured with an angle from the lower surface in a first direction that is tangential to a rotation of the rotatable disc. ### Claim 13 (depends on 12) The stationary sorting head of claim 12, wherein the angle of the first stripping ramp increases in a second direction that is a radial direction of the rotatable disc. ### Claim 14 (depends on 13) The stationary sorting head of claim 13, wherein an increase in the angle of the first stripping ramp is constant across the stripping area in the second direction. ### Claim 15 (depends on 13) The stationary sorting head of claim 13, further comprising a second stripping ramp located in the second direction, towards a center of the rotatable disc, from the first stripping ramp. ### Claim 16 (depends on 5) The stationary sorting head of claim 5, wherein the second stripping ramp is located in a counterclockwise direction in the first direction. ### Claim 17 (depends on 15) The stationary sorting head of claim 15, wherein an angle of the second stripping ramp increases in the second direction. ### Claim 18 (depends on 17) The stationary sorting head of claim 17, wherein an increase in the angle of the second stripping ramp is less than the increase of the angle of the first stripping ramp. ### Claim 19 (depends on 15) The stationary sorting head of claim 15, wherein the angle of the second stripping ramp is constant across the stripping area in the second direction. ### Claim 20 (depends on 11) The stationary sorting head of claim 11, wherein the angle of the second stripping ramp is different from the angle of the first stripping ramp.
