Blimey Bill, that's a hell of a list.
It's funny what you learn, we can all appreciate why loose change is called Shrapnel, but I had no idea of the etymology of the word itself:
"shrapnel - loose change, especially a heavy and inconvenient pocketful, as when someone repays a small loan in lots of coins. The expression came into use with this meaning when wartime sensitivities subsided around 1960-70s. Shrapnel conventionally means artillery shell fragments, so called from the 2nd World War, after the inventor of the original shrapnel shell, Henry Shrapnel, who devised a shell filled with pellets and explosive powder c.1806."
