Can you give us an overhead photo of the obverse like you did in the second image for the reverse? ~ Chris
Could be a lamination-related planchet flaw, I suppose. War nickels are probably the most lamination-prone US coin ever. Then again, it could just be damage. I dunno. My suspicions are that yes, it is an error coin, but only a minor error which adds no premium. Kinda neat, though.
You have a very good point there Lord. I didn't even think about a loss of lamination. I do think that these are for the most part the same thing though. http://www.error-ref.com/?s=Fissure
Interesting. I knew the word "fissure" as a general term, but did not realize it was categorized as a numismatic error type.
@Thanos Father, I used my magical moderator powers to correct your title, as this is a 1943-S Wartime nickel, not a 1947.
It was struck on a cracked planchet. Its only worth what a collector is willing to pay for it. Here is an example from my collection
Good call @paddyman98 . I thought I saw more of a ragged area on the rim. But also didn't know that there was a cracked planchet reference
