I wish I could get better pictures with this camera. But it just won't let me. I know in part the die was worn but why would it be raised on obverse side and nothing on reverse? Just asking! Let's see what the experts say. Not the expert imposters on Google. They all can't be right!
Short and sweet. Just like I like-um! I have others with a ridge ring. But not raised up like this one! Wish I could find my My micrometer.
Your ridge ring is more pronounced than most. Personally, I consider it a form of die deterioration and not an error and don't see it having additional value, but keep it if you find it interesting
It seems like this is more common on zinc cents than the older copper ones, I wonder why. It seems like the softer zinc would be easier on the dies. Maybe they are just able to use the dies longer?
I've not seen it in the older copper pennies yet. Yes, it's quite common on the zinc'ers though. I've come across plenty of those.
U would think if it's not legible from mint. It wouldn't be legal tender. But that's our government for ya!
