Authentic Spanish Colonial-Era Half-Real (1/2-Real denomination) Silver Shipwreck Cob coin in custom-made bezel setting constructed of silver, to be worn as a pendant. Sea-Salvaged from unknown/Unidentified wreck/source. No clear discernible design details, no visible date, but most likely minted in the late 1600s or early 1700s. No mint mark visible, but coin came from a group of coins that were said to have been minted in Potosi, but there is no way to verify this. Very worn and corroded, extremely prominent "shipwreck effect" type surface pitting caused by centuries of exposure to saltwater. Please see all photos for close-ups and different views and judge the condition for yourself based upon those images. Gross weight is 2.56 grams approximately. All items being sold "As-Is" and the photos are meant to serve as the primary descriptor.
