Circular, just over ½” in diameter. White metal, probably a tin-lead pewter alloy. Just remnants of the circular motif (cross and orb?) and radials to the edge. The top with a suspension loop is intact. 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 were, and sometimes, the whole corpus was preserved. The symbols are specific to the life and achievements of the saint. Pilgrims wore them strung as necklaces, on hats, or attached to their clothing.
