If you flip a nickel which sides going to come up more consistently taking into effect the width and the overall surface of the wind resistance passing through Jefferson's hair?
Not to mention the dates are going to be different on every nickel, considering also the E may flip it towards the left, rather then the P mints might ever so slightly do the opposite of E. But then again is there more E or P nickels? Might have to to some iteration of the years since it's came out also. As in the 1911 would be lighter on the left side towards the 19 rather then say 1999
