Sorry, die deterioration. When you suspect doubling go to Wexler or Variety Vista to confirm it. You should also include pictures of the coin full obverse and full reverse. We don’t even know the actual year, just your say so. And this is why you do it this way…imo…Spark
I agree with deterioration doubling. Worthless doubling Common issue on many Copper plated zinc Cents.
I would love to tell you that you did indeed find your first doubled die. Sorry but I can’t say that. What you have has already been stated and it is doubled because of a worn die. It’s called Die deterioration Doubling. It’s very common. Welcome to CT.
