It's where we got the term "Pounds Sterling" from. And I wouldn't mind getting a few pounds of sterling silver if that same value was here today - silver is currently more than $30 per ounce! Sterling a bit lower, of course.
Went through the first two years of school in England when my Dad was stationed in London, 1951-53. Learned to hate the verdamt pounds. shillings, and pence! Heck, they even had 1/4 pence! And learning to multiply and divide in three different bases earned me plenty of bloody knuckles from the teacher is a memory I'll never forget.
12 pence to a Shilling, 20 Shillings to the Pound, but 21 Shillings to the Guinea! Sheesh!
