It is a striking error not a die variety, so the denticle doubling will not be applicable to a particular VAM. I believe it is an ejection error (not my specialty, but I have seen this before, and it would not bring a premium for the error alone). Just ignore that part and look at the other features.
Almost all the 1880-P VAMs are doubled date there are a lot of those, check carefully for clashing that may point you in the right direction a bit faster if there is any transferred "M" or "E".
At vamworld they have offer some help to get you narrowed down, try this link to start. http://ec2-13-58-222-16.us-east-2.c...Sort_by_Date I see some doubling on the 0 for sure, but can't tell from these photos, looks like some die gouges in the tail feathers maybe, I can't tell if there is any clashing, 1880-P can be a challenge, when it's not one of the big or obvious ones.
