As the depth of the clashing is very light and as the remnants of the clashing is near the center, this is mostly likely the result of a dropped working die. This could have happened when the working dies were being stored, or in the coining press with the reverse working die in the lower position and the upper working die accidentally being dropped when being inserted into the die holder. On the first off-center clashing to the left, the remnants of the top of the spaces are much stronger than the rim edge. This leads to the conclusion that the degree of tilt was less than angle between the top of the spaces and the rim edge on the working die. For the off-center clashing to the right, the remnants show equal depth.
