This dazzling 1 reales replica pendant was inspired by a rough-hewn silver "cob" coin recovered by Odyssey Marine Exploration's founders during the first deep-ocean archeological excavation of a colonial Spanish shipwreck. Research suggests the sunken ship discovered near Florida's Dry Tortugas was part of the 1622 "Tierra Firme" fleet bound for Spain with New World silver reales, also known as "cobs."

These irregular-shaped pieces of silver were shaved from colonial silver bars, hand-hammered and crudely stamped with the Spanish seal and an assayer's mark. Like the recovered 1 reales it replicates, this coin is roughly the same size as today's nickel at a diameter of approximately 9/16 of an inch. Cast in fine .925 sterling silver and framed in 14-karat yellow gold, this striking piece of jewelry makes a timeless gift.
