To add, one of the guys I work with, he uses a Canadian Looney coin. That brought back a memory when I was coaching, a white hat had a looney coin similar, and he told my captain to call "Queen or Looney", and my captain said, "Looney, since I'm one anyway". That got a few chuckles, which became uproar laughter when it actually came up looney side, and my captain said, "just my luck!"
