I hoped that was the case. Perhaps one day, some error specialist such as yourself will actually discover a true doubled die that has the notches on both sides. What a treasure that would be.
or quad die. Point I'm making is this. Every DDO/DDR, TDO/TDR, etc. I've seen is doubled in the same direction. I'm going to start looking for doubling on both sides of the relief due to the hubbing going in one direction and then the next.
