Abstract: A modular currency bin has a pair of spaced end walls, a rear wall extending therebetween, and at least one support wall extending between the end walls and abutting the rear wall. At least one divider wall extends vertically parallel to and intermediate the end walls to define a multiplicity of compartments. One of the end walls has a pair of outwardly angled flanges extending along its side margins and the other of the end walls has inwardly angled flanges extending along its side margins and defining a channel therebetween configured and dimensioned to receive the outwardly extending flanges of another currency bin. Bins may be assembled in side-by-side relationship by interengaging the end wall flanges, and in vertically stacked relationship by interengaging end covers with the end wall flanges of the stacked bins.
