Hey, if you find someone who makes custom coins, I'd consider commissioning one with a figure head on one side and a whale on the other. "Heads or Whales."

Why?
My brother's girlfriend is a marine biologist who specializes in whales. Last Christmas I got a trophy base made then added a whale with a golf ball glued to it's blow hole. The inscription read "The sea was angry that day, my friend!" You must be a "Seinfeld" fan to appreciate the humor.

With great power comes Awesome irresponsibility.
