First thought it was scratches, but might be planchet flaws? Die cracks on front? Also, weird line next to the B in Liberty.
Not die cracks on the reverse as they're almost always raised . Some type of lamination flaw like Frank said .
The thought has crossed my mind.. but I am not seeing the evidence of "bad" fake as easy as you are seeing it.
I thought fake too , but when I looked it up there wasn't a '52 listed , which of course means nothing unless one comes up with a match . Tool marks that shouldn't be there are always cause for concern .
I think it was made for jewelry, if you look at the back ( Reverse ) it show signs of being a broach . where the leg feathers were, is where one side of the pin was placed and in the field is where the other end was placed, or somewhere real close to thoses areas ....
I've seen this before, I also collect gem stone and when I come across some rare stones, I go and visit my jeweler to set them and now and then he'll sell me small gold coins he was going to make into rings , broaches, Etc. The biggest one was a 20 dollar gold 1909-S but it came from a broach, the price was right and you know the rest ...
The spot on the left is simply how these coins look (flat area). The right side is what we were debating could be a planchet flaw.
I pretty sure this was something like a stick pin, back in the day . Here an image of the area where your coin was ground down so they could set one side of the base for the pin .
