One last thing to add.

For example the big doubled like 84-P (ear), 83-P (reverse) 55-P (obverse).... are from one die.

So, like on your 84-D, it can not have the same doubled die like the 84-P die-1.
That doesn't mean and can't have some different doubled die or even similar but it's no more likely to be anything simply because the big variety was from the same year from a different mint.

Not sure if I explained that well but so many times people post things asking if their coin is a big known doubled die but their coin is a different mintmark or one is a proof variety or bus strike variety. I'm saying any modern cent die variety is from one die, the one die is from one mint, it can be only the same type of coin (meaning proof or bus strike).
So for example if a proof variety is listed, you won't find a bus strike of that variety, if a P is listed, you won't find a D of the same variety.
