Shippwreck piece 1715 Spanish reale silver coin CP 704

THIS COB IS WELL WORN AS IT WAS EXPOSED TO THE ELEMENTS BUT SOME MARKINGS ARE STILL VISIBLE.

COB IS PURE MEXICAN SILVER REALE OF THE 1715 PLATE TREASURE FLEET, ALSO KNOWN AS NUEVA ESPANA (NEW SPAIN).

COIN SHOWS SHIELD OF HAPSBURG ON ONE SIDE,  THIS COB IS FAIRLY SIGNIFICANT AS IT DERIVES FROM A FLEET OF ELEVEN BUT ONLY SIX OF THE SHIPWRECKS HAVE BEEN LOCATED.

THIS COIN IS SHOWING SIGNS OF SEA WEAR AND IS NOT READABLE
