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.


  1. Begin with the quarter heads up.
  2. Flip the quarter in the air and let it come to rest on a surface (don't catch it).
  3. Repeat as many times as you feel like and record the results.
  4. Enter the data in our survey below.

* Number of Heads

* Number of Tails

* Number of Times it Stood on Edge
