There are no die cracks or clash marks on either side, however, by the time this example was struck, the obverse die was in the process of severe failure in the form of die sinking that creating a large bulge at lower left. Such die defects are most often given the name "die bulge" although it is actually just the opposite. The coinage die is starting to sink or collapse, creating the raised area on the coin.
