Can someone explain what happened here?

1. It looks like a doubled die with slight clockwise rotation. Doubling is most evident in the rays bottom left and ER of PERUANA.
2. The date 1946 has strong doubling in the 19 which I take to be re-punched numbers, while the 46 is crisp and singular. Note the rotation of the strong 1 while 9 is doubled but shifted left.
Opinions are gratefully solicited
