Is this a strike error? 0

This is the front of a 2000 Massachusetts quarter. Does anyone know what the circle imprint cutting through some of the letters is? Any insights are helpful! I’m completely new to this!

Welcome to the Forum-

Not an error. We see these quite often. That coin must have been on the end of a roll. It is caused by the coin wrapping machine  when it crimps the end of the roll. It is considered damage to the coin.

It's machining damage of some sort.
