The wonderful world of currency. I was a little spooked to realize I didn't know where the word "dollar" came from. "Cent" is a bit more obvious, but "dollar" is weird. After looking it up, it really is weird. We get our dollars from Spanish pirates - yarrrgh.
But American currency isn't the only ugly duckling in the pond. I also went digging on the British pound, and they have more skeletons in their closet than Vincent Price's birthday party. We try to standardize measurements down to the light second, but currencies are bloody strange.
Anyone curious about other currencies out there? I'd be glad to go digging. Historical dirt is my specialty.
