It can't be a D/D after 1989 because the mintmarks are on the hubs, aren't they?
It's either a die chip or two, split plate doubling, strike doubling, or a combination of all three.
How to find out . is it rare
Per Fred Weinberg, who is the expert, not rare or valuable.
Not rare, but nice photos.
Thank you all
