Not knowing the date of your coin, it could be anywhere from 19 to 52 years of circulation damage and wear. Pretty ordinary, if you ask me.
It's 1988 the thing that seemed most weird was in the thing the eagle holds it looks like there's the numbers 72
You've circled most, but not all, of the bag marks/contact marks on the coin. As mentioned above a few times, it's not an error coin of any type.....sorry
