|ROTATED DIE COIN CENSUS|
Census for US coins with major die rotations ranging from 90 - 180 degrees
|U. S. COINS WITH MAJOR DIE ROTATION|
Rotated die coins usually occur in two different ways, the first being the mint employee installs the die incorrectly so the obverse and reverse do not line up properly when the coin is struck and the second is when the die becomes loose and then moves a little bit as each new coin is struck. You generally can make a fairly accurate guess as to the rotation of a coin by looking at it but the only way to get an exact measurement is by using a device designed to measure a coins rotation. There have been several made over the years but the only one currently available is called a "ROTA FLIP" by LEROY VAN ALLEN. The following is a list of all rare coins and modern coins known with rotated dies and the approximate degree of rotation for each coin along with a grade if available. Where a coin is known to have more than one with the same degree of rotation all known grades will be listed. This list will in no way show all known types or dates of coins available as it will be a work in progress that will take many years and lots of input from other rare coin and modern coin collectors to be any where near successful. Help from any and all collectors who submit information will be greatly appreciated.
