1900 "Broken eagle" mechanical brass "dollar"

Mechanical brass "dollar" promoting William McKinley for president and Theodore Roosevelt for vice president, and disparaging William Jennings Bryan and Adlai Stevenson, 1900. Move the loop to 12:00 and it reads I'M ALL RIGHT / GOLD STANDARD MEANS A DOLLAR WORTH 100 CENTS MACK, TEDDY AND PROSPERITY. Shift the loop to the right and it reads WHERE AM I AT? / FREE SILVE MEANS A DOLLAR WORTH 50 CENTS BRYANARCHY AND STEVENSON. 1 1/2" diameter. Still works ok, but just a little bent.
