Error In 1993 Penny?

Hi, so I am kind of new to the collecting and finding values to coins kind of thing, and I was looking over these pennies that I found, and surprisingly I may have found a penny that may or may not have value to it.

So here in these two pictures I have a 1993 penny that has some scratches and wear here and there, but on the back the "S" and "O" of "The United States of America" seems a little bit worn. Is that caused by damage from over the years or is this some kind of error?

Thanks so much. Pictures are down below.
