This design was also struck in copper J1525/P1691 with at least 8 known.
A second obverse die with low date, head and less finishing in the leaves was also created and is described in Pollock as P1692-P1693. I believe this die was actually the first one created but was rejected. Only a single example was struck in both silver and copper.
