Mostly pounds and shillings. I thought 12 shillings to the pound but was corrected. (The 12 that stuck in my mind was the number of pence in a shilling; there were 20 shillings to the pound.)
Which reminds me, oddly, of Enid Blyton saying the dog's tail was wagging 19 to the dozen. I don't know why I always remember that, or what it has to do with the number of shillings to the pound. But if you have followed BritishSpeak since its inception, you know why an American is familiar with a British children's author. Back to money.
Anyway, the real questions I had were about what other money names meant, including slang. For example, Sherlock Holmes and H.G. Wells spoke of gold sovereigns, which I don't have a clue as to the value. I finally figured out what a quid was, but still don't know what a bob is or was or where the word came from. Ebenezer Scrooge gave the prize turkey boy half a crown for returning with the poulterer in less than five minutes, says Charles Dickens. I don't know what a crown is, money wise. If I did, I could surely figure out what half a crown was.
Let's not forget guineas. Nobody knows what those were.
I was force-fed a song in grade school about someone who had six-pence and seemed happy to have it.
The song "A Soalin'" (don't get me started on soul cake or carved turnips, please) mentioned a ha' penny. And my friend claimed to still have a farthing. What IS this stuff? What WAS that stuff, I mean.
We all agree that bobbies are named after Robert Peel, but I don't think bob the money is related. Whatever a bob is. Not my uncle, that's for sure.
I give up. I doubt if anyone remembers anyway.
The Telegraph, June 6, 2010: "Enid Blyton beats Roald Dahl and JK Rowling to be voted Britain's best-loved author." The children's authors were ahead of Jane Austen, William Shakespeare, and Charles Dickens. Another children's author, Beatrix Potter, also appeared in the top ten. I think all but Rowling and Shakespeare were paid in the old money at one time or another. Maybe Shakespeare, too; I haven't researched Elizbethan lucre.
