Really tough to see that with the photo , any chances of getting a closer photo of what you see exactly?
I tried to resize the photo after I saved it but , no go just got blurred out ...
It is a rather common Nickle date , and my guess would be a
Machine Doubling effect maybe .. or something on them lines where the die maybe slid or shifted alittle bit ? .. Just a guess but clearer photos would be a bit easier to really notice the finer details ...
