The Levin Catalogue is composed of two similar collections of glass and stone beads assembled by Moses Lewin Levin, a London bead merchant whose business operated from 1830 to 1913. A total of 621 beads of 128 different varieties makes up the collections which can be dated to the period 1851-1869. Although the beads are recorded as having been used in the African trade, several have counterparts at North American sites, thereby making the catalogue a potentially valuable research tool for those involved in the study of North American trade beads as well.
