Gold Price 1663-1800
Data by Lawrence H. Officer, 2002

  Gold Price 1715-1800
Lawrence H. Officerlink offers the London market price in pounds, shillings and pence for the standard ounce from 1718 onwards, and he gives the equivalent sum decimalised for the modern fine ounce. Before 1718 the official gold-price seems to have followed the market price relatively closely, which can make up for the loss of data - see the table bellow.
The fluctuation of the gold price was remarkably moderate. From July 2003 to July 2004 the gold price fluctuated between $ 342.50 and $ 427.25 per fine ounce. If we take $ 400 as today's price (July 2004), £1 of the year 1709 could buy as much gold as $ 91.98, € 75.92 or £ 50.18 today.
