I'm going to throw a wild guess out there. Based on the coloring of the coin, along with the coloring of the indents of the coin on the obverse (very black indents, almost like oxidizing), I'm going to take a guess and say it's a Struck on Copper (CI-Ni) Wartime Nickel. Similar to this one: https://coins.ha.com/itm/errors/1944-p-5c-jefferson-nickel-struck-on-a-copper-nickel/a/349-10306.s
I took another photo. Problem is it is an absolute give away. So here is a clue. Why is the coin at a slight tilt in the slab? @paddyman98 @JCro57 Do you see the error, and possibly have any better clues to help? @Mountain Man @alurid @Seattlite86
Yes, this is a split planchet after strike. Or a clamshell. This one is barely staying together from what I can see thru the slab it is still connected from 1 o'clock to about 3 o'clock on the obv,
You would have to guess the grade on the slab correct. And I don't know, maybe an atta boy, or a pat on the back, maybe a high five.
I saw it right away on the photo of the reverse, before seeing the added photo. Very cool clamshell error! And looked low XF, unlike my damaged mercury dime, which is still cool to me, nonetheless. Awesome coin, where did you pick it up? Mine for reference:
At a brick and mortar. This dealer has a lot of good well priced inventory that turns quick. I hardly ever see the same coins twice.
