I could understand this coming back in an MS66+ holder, but MS66, I don't think so. I sent it to PCGS because I had other coins going there. This coin is going to get cracked and sent to NGC next.
With all those marks on the legs of the eagle, absolutely no way this ever gets 67. Honestly, the only reason it got 66 is because the marks are hidden by the design. You take those exact same marks on George's cheek, and we're talking 65.
