Sacagawea mint damage coin?

Hello I was hoping the experts on this forum could help me to give me some Insight. This coin was collected for me by a teller at seven eleven. It's interesting that the cut marks on this coin look like they would be after menting process but they're polished into the coin. Where you would expect to feel rough edges the coin is smooth and polished smooth. Has anyone seen anything like this? Please advise.
