It is apparently from the early 19th century and is english slang for a half-penny. Don't worry, my head is full of useless trivia.
Useless trivia is perfect for filling conversation silences. For example, did you know the worlds smallest tree is the arctic willow, which grows to approximately two inches in height and is a favourite snack of Musk Oxen? I've thrown that one into the odd stale conversation mix before. Doesn't do much, but it gives me the giggles with the 'wait... what?' expressions
