Major mint errors in the U.S. Peace Dollar series are very rare. There are only a few known off-centers, broadstrikes and double strikes. Peace Dollar mint errors are many times rarer than Morgan Dollar mint errors. This is an unbelievable and unique Peace Dollar that was double struck. It is a flip-over since the struck coin flipped over but remained in the collar. It was subsequently struck again and rotated 270 degrees between the strikes. There are a few double struck Peace Dollars known but the second strikes are 80% to 95% off-center and several have uniface reverses. This is the only known flip-over double struck Peace Dollar. It was authenticated and certified AU 58 by PCGS. It is unique since it is double struck in the collar and is also a flip-over. There is considerable detail remaining from the first strike on both sides. Especially on the reverse which shows the entire portrait, eyes, nose, mouth, lips and chin from the first strike which was struck by the obverse die. The obverse also shows detail of the Eagle's wings and the rays of the sun from the first strike which was struck by the reverse die. This is truly a unique and dramatic major mint error in the Peace Dollar series.
