LOL... I used to be an educator of photography at a University, here in the U.S. and would only flip dimes... as a half dollar was usually too precious to put at risk of going down a heat vent! :::grin::: Okay, Truth be told...
I never did resort to the filp of a coin to "confirm" a grade.
Your picture is clever, creative and smacks at the truth...or at least the truth as to how some students think their grades are being determined.
really funny shot, made me laugh, seems like the paper in the top corner is a little too bright for my taste. as a student, sometimes i feel this is how teachers grade!! great shot
