1972 s memorial penny I think it possible ddo so I want to see if and one agreed with me on this coin
Usually if there is a DD which is not mechanical doubling, die deterioration or w/e, if is very obvious to see. And the DDs that are not obvious are worth less. The more dramatic the DD ( 1955, 1969-S ) the more valuable they are. I mean I see a little bit on the 2. But nothing on the lettering.
Did you find any matches on www.doubleddie.com or www.varietyvista.com ? You've been here for a while and hopefully know these sites should be your FIRST stop These sites offer a tremendous amount of information about doubled dies. Study them
I study variety vista and wexlers but some coins I would call doubling lot of times it comes out to be die deteriorating
I right clicked and opened the image in a new window. Then I held down the control button while using the scroll on my mouse to zoom in. It doesn't look like genuine doubling to me, but it never hurts to get more than one opinion. Keep searching!
When attempting to get verification on something like this, you should post FULL IMAGE photos of the entire coin, obverse and reverse, and then clear closeups of the areas that you question. For me, it's a solid NO on your coin.
