Circular, about 5/8” (0.66”) diameter. White metal, probably a tin-lead pewter alloy. The front with a cross in a circle, the beam terminals, crutched as with the Jerusalem cross. Hound’s tooth border. Reverse plain. The top with a flared thickened end nub used to sew the badge to clothing, particularly hats. These were produced in the Holy Land for pilgrims who wore them at home as prestige symbols. They were sold at shrines of saints where holy relics of the saints, sometimes, the whole corpuses were preserved. The symbols are specific to the life and achievements of the saint. Pilgrims wore them strung as necklaces, on hats, or attached to the clothing. Fine patina.
