This is a "restrike" made in the late 1860s or early 1870s from the regular die having Liberty incused on the shield. This is Judd's so-called straight date variety.
To my knowledge, no originals were ever made using this reverse die. In fact, I believe that this die was actually finished many years later either in the late 1860s or early 1870s. This appears to be the last use of this obverse die as there is a crescent shaped bulge or clash to the left of Liberty's right arm, as shown below courtesy of PCGS, which does not appear on any other restrikes using this obverse die.
