this plate celebrates the 200th Birthday of the United States.  It is 10 1/2 inches in diameter.  There is a 1 1/2 inch crack at the bottom, it does not go through the plate. It is a surface crack. It has a light green ring and vibrant red, white and blue flags and the liverty6 bell.  No markings on the back side of the plate. Sorry for the blury pictures
