Oh ok thank you. I have had this coin in my set for long while. It was the first Morgan I got. Bank gave it to me. I have never polished any of my coins I was just wanting to know if that was a error on Dollar and by the east side of arrowheads. Now you got me thinking. Fist time it's been out of its case since I got it. Thank you for the explanation I will take it into St Louis and have someone take a look.
