1984 D DDO Not Sure Which?

This is a Denver mint coin, so consider the location of the mint mark. It looks like 004 is closest in location. But check to see if the hub doubling is the same. The other 001-003 locations of the mint mark are not close. But it still could be a new die. But check to see if you can find any markers that match or die flow/events that might match with your coin. But the hub doubling on all devices should be a match in order to be this die. Die wear is also something to consider as to whether it matches the 004.
