Hattie Carnegie Spanish Cobb Coin pin. The brooch is a hammered silver cob money reproduction of a coin that was recovered from a sunken Spanish Galleon during a hurricane dated all the way back to 1731. The ship sunk off the Florida coast and was found in 1733. Carnegie designed the brooch as a reproduction of the coins found on the Galleon. This brooch has a top section made to look like a balcony surrounded by foliage with a plaque that has a lion on it. This section suspends the silver Spanish Cobb coin design with a faded hammered design on it. The back has a pin and locking "C" clasp and the signature "Hattie Carnegie" within an oval cartouche. This brooch measures 3" long by 1 1/8" in width and the entire piece is in excellent overall condition.
