While just about .75" tall, the workmanship of the fine detailing is extraordinary. The pin is 1/8" deep and we will describe it layer by layer, back to front. The metal areas likely have a gold wash. There is a "T" hinged vertical pin with catch below. The reverse metal has slightly convex surface on each of the five arms of the star. The front metal star arms have more pronounced convex surfaces each covered with engraved accent lines. At center of the star is a raised ribbed collar about 1/32" deep and set within this collar are 20 seed pearls each about 1mm. Under magnification, three have surfaces smoother than the others and these are possibly replacements. The pearls surround an opening of .25". Within this and slightly recessed is a glass cover over a black and tan paper print of Washington which has lines and accents like those seen on a steel engraving. The background has fine horizontal lines around his image while the outer border has a circle of white circular lines against a black background. This print is precisely in the style we've seen on 1832 era Andrew Jackson pewter-rimmed mirrors and therefore we feel this was likely used to commemorate the 100th anniversary of Washington's birth, perhaps used by a Washington Benevolent Society political organization member. These groups honored Washington's birthday with annual February, 22 orations and with a particularly large celebration in 1832 as evidenced by the many silk ribbons shown in the Sullivan/Fischer book. An exceptional and rare pin. The only example known to us. Displays Mint.
