Coin from the famous ship El Cazador, which sank on January 11, 1784. More than 200 years later, on August 2, 1993, a fishing boat accidentally discovered silver coins from the El Cazador wreck 50 miles off the coast of Louisiana. The silver coins were found at a depth of approximately 90 meters. One of them is being offered for sale, along with documents confirming its origin from this famous ship.
