I REFERENCE MONEY IN two different ways in this book: written out (i.e. one pound) and numerical (i.e. £1). Sometimes, the pound sterling was written l (i.e. 8l). I do not use that style in this book. However, I thought you should know, especially if you find yourself looking up a term or item that is mentioned in the book.
d – This means penny or pence. It was abbreviated in the period with a d not p, as in a Roman denarius not p as in penny. In this book, you will find Miss Knight writing down 9d and then calling it nine pence. It takes twelve pence to make a shilling.
s – This means shilling. Four shillings is written 4s. Twelve pence made a shilling. Twenty shillings made a pound.
Guinea – In 1810, the year that this book is based, a guinea was worth twenty-one shillings.
I hope that helps!
