Your correct this is absolutely NOT a high relief proof but rather maybe a low relief satin proof.

This coin is a EDS for sure. No signs of die cracks chips or other obvious die wear are visible on the coin.
If you compare the coin from this post with the Low Relief satin proof from pcgs the strikes match when you take into consideration wear. From rim to central design elements all details of the intended design are visible on this coin with the exception of wear and contact obstructed areas. My coin appears to be au/xf in grade. Some areas still show tight well executed polishing. Due to surface condition it's EXTREMELY hard to match polishing lines. Ill admit The chances of me finding a satin proof are next to none. From my understanding all
Peace dollar dies had a satin finish to begin with. To my knowledge the difference between a proof and a business would show in the surfaces and strike. Even being whiped and circulated this coin still shows a surface bellow that leads me to believe its not normal. I can't say for sure ive encountered this look on a
Peace dollar. It looks wrong, The last polished peace I seen was easy to understand it was damaged. This coin just looks off. So maybe a proof maybe not?
