Prices
In the Blathwayt family's trade bills money is stated in pounds (£), shillings (s) and pence (d). There were 240 pence in the pound and twelve pence in the shilling, and twenty shillings to the pound. This system was used in the United Kingdom until 1971.
The list of prices below is collected from the trade bills in the Fitzwilliam Museum's collection, and so are most accurate for the period 1764-86.
More information about money in this period as well as images of coins and tokens can be found on the Money section of the online exhibition.
