This piece has been misdescribed as an 1838 trial P3052 by Pollock but it is actually a trial of the 1840 with drapery design struck in white metal without date. We have therefore assigned it as P3072 to more correctly attribute this die trial.
P3052 may not exist although Taxay list an 1880s auction for it.
The present piece is believed unique and was part of the materials purchased by the Library Company of Philadelphia from Maxwell Whiteman. It is listed as inventory #15.
