I didn't think the weight can make a difference on a coin. But it does. When looking at some missing clad images on heritage coins, even one layer of cladding missing affects the strike of the coin on both sides:
What-Happened-To-This-1972-D-LMC?
What-Happened-To-This-1972-D-LMC?
What-Happened-To-This-1972-D-LMC?
Note the missing cladding on the obverse, make the strike weak from just that much metal missing. With that information I fee the Op coin is under weight/thickness.

Double check the weight, then I'll move onto other possibilities like grease and the like.

The bust has the largest cavity to fill and a thin planchet will generally leave weakness opposite of it. Thanks, Doug.

Weight is the critical piece of information still missing

I'm hoping to have it weighed over the weekend. Chuckster has offered to weigh it for me. I'll PM him over the weekend but have to head out to work now. Thanks for all the replies. I will have to invest in a scale and a good camera soon.

You might take it to a jewelers to get a weight there?

The missing details on the reverse are most likely due to "grease" clogging the die. The obverse periphery shows the effects of intentional die abrasion.

In the multiple examples of this I have seen, admittedly not as pronounced as this one in the OP, I find it very interesting and curious that the grease on the die seems to gravitate to the same areas (center steps and center top of the memorial). Why is that? Is there something about the die design or the nature of the strike which causes it?

Grease of the right viscosity tends to migrate to areas of lower effective striking pressure, like the areas on the reverse opposite the bust of Lincoln. In fact, a large amount of migrating grease will generate a vague, incuse impression of Lincoln's bust (a "greasy ghost").

The coin did weigh in normally(3.05 grams). Thanks Mike Diamond, is it even worth putting it into a 2x2 or are they too common to keep? Thanks everyone for your replies. Got a good bunch of people on this forum.

I suspect many would toss it. I would keep it! For me, it is interesting and may be only worth 1c, but that is not the issue for me.

I would keep it because of the unique look of it. Not that there is a premium for this, it would make a neat item to show to new collectors.

I would 2x2 it and put the date and title it appears here on CCF as a reference.
