Morgan's second obverse design of this type with pellets between the words in "E Pluribus Unum" combined with his reverse without pellets before and after "Five Dollars".
It is unclear if this is a second obverse die or the original die used on J1568-J1569/P1758-P1760 with the pellets added later.
These were struck on thinner and slightly wider 25.5mm vs 21.5mm planchets than the regular issue.
This variety was discovered by Andy Pollock and thus was unknown and unlisted in the first 7 editions of Judd. It has since been assigned J1573A. So far, 4 examples are known.

4) Superior's 1/03, Heritage 4/18 - PCGS64BN and is presently slabbed as a J1573/P1762 in error.
This obverse die was also used on J1570-J1571/P1764-P1765 and J1572-J1573/P1761-P1762 and the reverse was also used on J1568A/P1759.
A copper obverse die trial JA1878-4/P3461 is also known.
