Hard to tell with this one by pictures.
There are many things to consider. Had this coin looked this way and been in higher grade it may have been easier to determine. But because it has been circulated that wear can hide what we would be looking for. I would have to have such a coin in my hands to view it myself under a scope. However, even so, I can tell you now that even IF it were an error, it would not be worth much. And the reason for that also has to do with a number of factors - particularly, the fact that it is as worn as it is.
I am glad to share my knowledge of coins so that more people know more about what they are looking at when it comes to coins. It is a learning process. It takes time and patience. But it can be fun to learn these things along the way. Best wishes,
