This pattern combines an obverse similar to that used on J661-J663/P734-P737 combined with the regular reverse die.
Examples are known in copper J779/P764 on both thick and thin planchets from two dies differing in date placement as shown below courtesy of PCGS.
The first has the date low and to the left with the number one under the point of Liberty's neck, the second has the date more centered and the number one is clearly to the right of the point of Liberty's neck.
About a half dozen are known combined most, if not all, appear to be bronzed.
The listing for an aluminum example J780/P765 is not confirmed and may be a misdescription of the 1868 version J663/P736.
