This American coin silver "Castle Top" calling card case has an architectural view and was made by Leonard & Wilson of Philadelphia. The case is rectangular with shaped edges and a hinged lid. There is an embossed design with floral scroll on one side on the reverse is a gothic building with arched windows.
The Leonard & Wilson firm of Philadelphia made calling card cases with views of important American buildings in the mid 1800s, similar to the sterling "castle top" card cases produced by Nathaniel Mills in England depicting European buildings (not all of them castles).
Although this case is unmarked, the embossed floral decoration is the same to those on several marked Leonard & Wilson examples. It's in very good condition with a few dents at the corners. It measures 3 5/8″ x 2 1/2″. 1.4 oz. troy. Circa 1850.
