This is just a minor point, but you could flip a coin (many times, of course) to determine if it was exactly balanced, and people have done just this, and it turns out most coins are not balanced. And (hopefully) Nevada Gaming Regulators do the equivalent when they test machines for randomness. Or do they just outsource the job to China?

The wikipedia article:
http://en.wikipedia.org/wiki/Coin_flipping
says most people coin flip with biases in the range of ".495 or .503".
