Copper plated zinc cents, such as yours, can easily have plating issues that disguise themselves as errors. At least to the novice. Once you have learned enough about the manufacturing of coins, the more easily you will recognize these plating problems, and how they manifest visually.
Another thing that you will learn is recognizing mint marks. Each coin type has its own size and design mint mark. Historically, when marks were applied at individual mints, we would see them improperly applied from time to time. It is completely different today, since the marks are incorporated as part of the die design, and not applied separately.
Time for more coffee.
