Having dealt with the mystery and perhaps myth of "VIGO" it seems pertinent to look at the other privy mark of the times - "LIMA".

Peter Seaby ... says "In 1745 a great treasure of silver coin had been seized in the North Atlantic by two British privateers, the Duke and the Prince Frederick, from two French treasure ships that had come from Peru. This booty was transported in forty-five wagon loads from the port of Bristol to the mint in London. As the booty principally consisted of 'piece of eight' bearing the Lima mintmark it was requested that coins taken from these prizes might bear the name 'Lima' to celebrate the exploit."

The coins which bear the 'LIMA' privy mark are gold 5, 1 and ½ Guinea pieces; plus silver Crowns of 1746, Half Crowns of 1745, 1746/5 and 1746, Shillings of 1745, 1746/5 and 1746, and Sixpences of 1745 and 1746. All from the reign of George II.
