This is the small change from the Great Age of Piracy, the beer money of their time. These little coins are irregular in shape and were usually not made on a circular coin press. They were hand cut from copper plugs and stamped with the seal usually indicating the value of the coin and the reigning sovereign of the time. Some were over-stamped at a later date and revalued. These are generally in two to eight maravedi denominations and date from the reign of Carlos I (Charles I), 1526-1556, up to Carlos III, 1759-1788.
