This unusual coins appears to have an extra S stamped in the obverse die over the left fleur of the crown. Additionally, the hYB has slipped, obscuring the initial cross. This is perhaps a result of a lamination in the obverse die folding over. Mint workers apparently used an S punch to secure the damaged section to the intact part of the die.
