Circular, 5/8” (0.63”) diameter. White metal, probably a tin-lead pewter alloy. The front with a cross within a circle surrounded by a motto or ciphers. The wheel possibly emulating the Wheel of Fortune as Pagan beliefs were incorporated into Christian religion. Reverse is plain. 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 corpus, were preserved. The symbols are specific to the life and achievements of the saint. Pilgrims (known upon their return as “palmers” and thus originating the surname Palmer) wore them strung as necklaces, on hats, or attached to the clothing.
