The flying eagle half dollar from the regular obverse die with Liberty incused on the shield. This obverse die is Judd's so-called straight date variety. To my knowledge, this is the only pattern made from this obverse die which is an original actually struck in 1838. Judd and Pollock lists originals and restrikes existing but this is an error caused by a misunderstanding of the dies involved. Both designs with the flying eagle reverse are originals! No light weight restrikes have ever been confirmed. About a dozen are known with the former Garrett coin being an especially beautiful example. The illustrated example, from the Smithsonian, is a mint error in which the reverse is double struck with about a 20 degree rotation between strikes as shown in the image below courtesy of Rick Kay. The original image is most noticeable below the eagle's tail feathers as it touches the "R" in "Dollar". This design was also made using the obverse with Liberty raised on the shield, the so-called 'curved date' J79/P89. To see both obverse dies side by side, click here.
