      The first strike was normal. The second strike was an in-collar uniface strike. The reverse face (bearing the hand and struck by the hammer die) was covered by another planchet and the two were struck together. You can tell this is the case because the reverse face shows a slightly undulating topography and the reverse design is slightly distorted. The die-struck obverse face shows close doubling.

      The third and final strike was off-center and an "invisible strike". During this strike the minimum die clearance had increased to just about the thickness of the coin. Another planchet intruded into the striking chamber, leaving an indent on the reverse face. The intrusive planchet created enough resistance to the impact of the anvil die that the latter was able to leave a strong die-struck design on the obverse face. The only other sign of the third strike is on the design rim, which carries a die-struck design on both faces. The aggregate height of the design rim was evidently great enough to slightly exceed the minimum die clearance.
