What do the letters LSD stand for in british pre decimal currency?

* L - Pounds (the main unit of currency)

* S - Shillings (20 shillings made up one pound)

* D - Pence (12 pence made up one shilling, so 240 pence made up one pound)

So, for example, £1.10.6 would be read as "One pound, ten shillings, and six pence".
