Test the Fairness of US State Quarters

Main Project Information
Goal Test for the fairness of the new state quarters.
Task Flip quarters and report your heads and tails.
Where Global, anywhere on the planet
Description

If you flip a quarter many times, it should land heads up just about as often as it lands tails up, assuming the coin is fair. But with so many different state designs, it's not clear that all U.S. quarters are fair. Help us check by taking a few moments to flip some quarters and report the results below.
