The designation is handwritten on the card. As the same designation is written in the same handwriting on cards with the same inscription held by different institutions, it is likely they were penned by whoever prepared all the Levin Co. cards in the 1850s-1860s rather than someone at a museum at a later date. They all appear to be presentation pieces, especially the ones mounted in boxes. Since Levin was a long-time dealer in African trade beads, one would think the attributions hold some validity. But certainly the beads could have been used to barter for other things at different times in different locations.
