MEXICO 8 REALES 1682 JOANNA SHIPWRECK COB 8R SPANISH COLONIAL SILVER COIN

 An English East Indiaman on her way to Surat on the west coast of India, the Joanna separated from her convoy and sank in rough seas on a reef off the southernmost tip of SouthAfrica on June 8, 1682, sending 10 people to their death. Eventually 104survivors reached the Dutch colony of Cape Town, from which a salvage party was soon dispatched. The Joanna’s cargo consisted of 70 chests of silvercoins, of which the salvage party reported having recovered only about 28,000guilders’ worth. In 1982 the wreck was rediscovered by a group of South Africandivers led by Gavin Clackworthy, who brought up silver ingots (discs) and morethan 23,000 silver cobs, most of them Mexican 4 and 8 reales of Charles II ingenerally low grade, but a few showing bold, formerly very rare dates1679-1681. Over the past two decades, these cobs have entered the market from both private dealers and auctions, but always in relatively small quantities at a time. Almost all the coins are in very worn condition, usually thin and nearly featureless, but without the heavy encrustation and pitting that characterize Caribbean finds.

THIS COIN, CALLED COB, WERE MADE FROM SLABS OF SILVER.  WHICH WERE ROLLED INTO 

 

ELONGATED SHAPES OF VARIOUS THICKNESSES SLICES WERE MADE BY METAL  SHEARS OR

 CHISELED BY HAND TO ACHIEVE THE PROPER WEIGHT.

THIS PROCESS ACCOUNTS FOR THE IRREGULAR EDGES. THE BLANKS WERE HEATED AND ANNEALED,

 THEN HAMMERED BETWEEN CRUDELY

ENGRAVED DIES. THE COINS WERE MINTED IN THE SPANISH AMERICAN COLONIES MADE  WITH

  POOR  WORKMANSHIP  AND WITHOUT PROPER

EQUIPMENT OR SUPERVISION.  OFTEN  THE COINS WERE STRUCK BY INDIAN  OR SLAVE LABOR.

    THE SPANISH AUTHORITIES WERE UNCONCERNED WITH THE SHAPE OF THE COIN ONLY WITH THE

 FINENESS AND WEIGHT, WHICH WAS

  GUARANTEED BY THE ASSAYERS MARK.
