RARE, 8 PIECE BICENTENNIAL (1776) plastic coaster set in Red, White and Blue

It is used but in good condition with the exception of one red coaster, which has a break in it, but it is fully functional. Each nested coaster (3 red, 3 blue & 2 white) features the number 76 and the image of the Liberty Bell. The number 76 has small red stars embedded in the design. Each coaster measures 3 ¼ inches in diameter. The set measures 4 ½ inches to the top of the wire frame which is a little blotchy due to its 47 years of existence. (SEE PHOTOS.)
