Just an update. The coin came back from NGC as authentic and received a grade of "Uncirculated Details" scratches. There are a few obverse scratches on the coin with the biggest between R and T of Liberty and a couple of minor ones above the Motto. Reverse is very nice though. This coin isn't listed in the Rotated Die Census nor does it come up in an internet search. At is point it may be the 1st reported.

"Based on your pic and the orientations in your first post, I would say it is rotated approximately 90° CCW. Technically, that's the same as 270° CW, but I think choosing the lowest number is most reasonable."

I still think it is either 90 degrees clockwise or 270 degrees counter clockwise.

My thinking is rotated dies are generally referenced from 0° to 179° CW or CCW, because if the die or dies are securely set in the tool insert at X° CW or CCW. The resulting strikes should remain constant, no matter if its set at 0° or 179° or anywhere in-between. A 180° rotation is typically indistinguishable concerning direction.

If the die is loose or has free movement in the tool insert. Then it could potentially rotate in either direction until discovered. Could be 90° CW or 450° CW or vice versa CCW.

Would need to have been present to witness, which die or dies was out of alignment as well. Thanks, Doug.

edit: to notch it down one degree above.

PCGS and ANACS list the degree of rotation going Counter Clockwise on their holders. NGC doesn't denote the degrees on theirs.

Does PCGS and ANACS list CW or CCW degree rotation past 179°? I don't recall seeing it without something indicating direction. 180° can be the result of one die or the other, or both dies moving simultaneously. So no direction is typically labeled, unless some form of die or strike marker is present, no known verifiable direction can be established.

Examples of Morgan's listed from PCGS Set Registry.

NGC made following comment in the below Presidental $1 Error Coins article.
https://www.NGCcoin.com/news/article/459/

Quote:
This next error is caused by the dies becoming improperly oriented in the press. This results in what we call rotated dies. We call them rotated dies and not rotated die as there is no way to tell if one or both dies moved in the press.

Thanks, Doug.
