The shield design with small motto and split date combined with the regular stars and rays reverse.
Examples were struck as follows:
Nickel J497/P583 with about a half dozen known.
Copper and/or Bronze J498-J499/P584 with less than a dozen known.
Incomplete white metal obverse splashers, P3278 and P3279 are in the collection of the Library Company of Philadelphia.
The obverse die contains a die cutting error. The motto was started too far to the right in a location similar to the regular 1866 shield nickel obverse die and then corrected. The second leaf points to the remnants of the letter "T" as shown in the image below.
