a swap friend of mine (Ina Huitema) has documented those interesting double dies. I suppose there must have been at least 2 different dies, where the engraver managed to create:
1. a double 1 and two well separated second 9's in the first die
2. only a kind of joined second 9's in the second die
3. maybe a perfect die as well, without any doubling in a third die, but we haven't found any yet.... do you have any in your posession?
Do any of you have any other explanation of this starnage doubling, since it cannot have happened when striking the coins (my humble opinion)?
