Circular, over 1/2” diameter.  White metal, probably a tin-lead pewter alloy.  The front with a six point star within two concentric hatched borders. Reverse with a variant of the same theme.  The top with a flared thickened end tubular bail, with small stringing hole for a wire, for suspension, 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, sometimes, the whole corpus 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.
