Clump of 5 silver coins: One Spanish colonial cob 8R, two English shillings and two English sixpence (probably late 1600s). 125 grams total. Rare as a mix of types and nationalities, with some details visible on all but also worn and corroded and dark, each one with its bottom third to half solidly embedded in the thick tan matrix, overall an attractive and impressive display. Recovered from: Association, sunk in 1707 off the Isles of Scilly, southwest of England ($500-750)
