Looked at all your posts and really can't tell anything as the pictures are too far away and lack details. It is also helpful to let everyone know what exactly you think you see so not guessing what to look for. You'll get the hang of it. Welcome to the group.
What do you see that makes you think it's an error. A little direction, and better pictures, would be helpful.
That is a nice honest Ike dollar. Certainly a cool collectible. But keep in mind too.... These coins see unlimited variations in environment. I have found coins glued with old soda and heaven knows what else to the bottom of a cup holder in old cars I worked on that that tend to present themselves rather odd. Look, numismatics is made up of a very rich history lesson in the form of coins. And an infinitesimally small fraction of that rich history has anything to do with errors or double anything. View your coins more from that perspective and less from the error perspective and you will enjoy this hobby much more.
