Morgan's first obverse design of this type without pellets between the words in "E Pluribus Unum" combined with his reverse with "In God We Trust" above the eagle's head.
These were struck on thinner and slightly wider 25.5mm vs 21.5mm planchets than the regular issue.
About a dozen are known, several of which have been gilted.
This obverse die was also used on J1568/P1758 and J1568A/P1759 and the reverse was also used on J1570-J1571/P1763-P1764.
