This is the coin that Two Face uses in Batman: The Animated Series. I recreated it for a cosplay, the size is roughly the same as a US dollar coin. It has two versions, one with hole for the eye, one without a hole. I would recomend printing it with the scarred side up for best results.
And remember my friend, good heads you live, bad heads you die.
