Rotated Reverse % needed

    What percentage of rotation is considered an error for a resent proof or business strike coin? Would proofs and business strikes with rotated reverses be judged the same since proofs are fewer in numbers minted? I realize that a 90 or 180 would be major I'm sure but is there a quality control guide they use? Would say 5% or 15% be acceptable in any proof since they are supposed to high quality?

    Thanks Kent

    I think mint tolerance is around 15°, but they generally don't command a premium unless they are rotated 90° or more.

    Since proof coins are processed by hand, you might find someone who may be interested in a proof coin with a rotation of less than 90 degrees. All you need is two bidiots chasing the same coin, and there is no telling how much it might realize in an auction.

    Each series might be different, with the Kennedy half dollar there are several collectors interested in rotated dies between 45° and 315° with the highest premiums for the coins closest to the 180° mark.

    When talking aboutthe amount of rotation - we use degrees, not percentages. As stated, demand picks up at 90 - 180 degrees. For dollar coins, generally anything more than 45 degrees is collectible. For nickels, for example, 45 degree rotations are nothing less than common.
