Question! Are you searching 1971 as per your title, or 1972 as per the coin? It looks like this IMO. The mintmark position is right. Wait for other far more experienced though. http://varietyvista.com/01b LC Doubled Dies Vol 2/1972DDDO002.htm
There are so many of the 1972’s that are a Doubled Die and they all have different features. It looks like it but I couldn’t tell which variety it is. Please get it checked out more closely.
It is not a true doubled die,IMO, it looks like a die deterioration doubling. Yes I know its in VV listings, but the photos do not show true doubled die characteristics . Jim
A true doubled die has 2 separate strikes of the same strength, so any lettering should be the same heights and overlap. I have used this photo so much , I apologize to those previous. Notice the 955, see where they cross they blend as they were struck by the same die. The 5's show the same thing. Lettering the same height so they blend since the same die is used twice ( double). Jim
I'd respectfully disagree. The requirement that true doubling be of the same height and strength is a widespread misconception and overgeneralization. There are many classes of doubled dies each of which has its own cause and appearance. What you said is true of many doubled dies but not all. Take, for instance, this doubled die I discovered on a 2019-P nickel. The separation is clear, and it is obviously not a die deterioration issue: (Images from https://www2.briansvarietycoins.com/listings/view/1887) The doubling is not the same height, it is in much lower relief. The doubling is not an effect of striking, but rather of doubling occurring in the hubbing process. Variations from what you are discussing can be accounted for by tilting, expansions or contractions of the die or hub, and many other variables in the hubbing process that can affect the appearance of a doubled die.
That 2019 is a single-hubbing. See here: https://doubleddie.com/58201.html. When doubled, those mimic strike doubling. Jim's right on the double-hubbed. There's no misconception. We've gone over this countless times. That 1972 was double-hubbed, while yours was single-hubbed. And that's it, in a nut.
