This is a very unique piece that was part of a sign from a bank or other institution. The dollar sign is cast iron and would have been attached to the building using the iron wedge in the center which would have fit in between bricks or stone where joined. Found in New York City this piece is from the 19th century and is in wonderful condition with one very minor ding in and edge.
The $ itself is 10 1/2" tall x 8" wide and 1 1/2" thick. Overall height is 12" tall 8" wide and 3 1/2" thick. Weight is 15 lbs.
