Circular, about 5/8” (0.67”) diameter.  White metal, probably a tin-lead pewter alloy.  Both sides identical with addorsed roped edges forming chevrons. The field with a cross with center nub and nubs between the beams cumulatively representing the five wounds of Christ. The top with a flared thickened end tubular bail, with a small stringing hole. 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 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 the clothing. This example is the best preserved that we have seen.
