1969 (S) Lincoln Penny Doubling Error. Grade Not Sure Red/Brown?

Well, this is the common machine-doubling, and believe us when we around here say that the big DDO is glaringly obvious (and insanely rare ), the whole coin got class-1 rotated dramatically.

As to grade, looks high AUish to me...

Yes, machine doubling--not uncommon with '69 S cents. To me, grade would appear to be mid-AU.

this is Machine Doubling.

Knowing what to look for on these rare DDO's will help you see why your coin is not DDO:

Note the spread on Liberty and the Motto? That is what to look for on these. Machine Doubling does also happen on th the 1968-1972 cents as a common event. But MD is caused by the machine, not by the die. So these DDO's can show Machine Doubling on this year:

Not the date on these images. These are all doubled dies, but there is also Machine Doubling on them as well. The Post strike movement by the machine causes Machine Doubling, but MD is never part of the doubled die. MD is an alteration of the struck coin, normal or not. So MD is never a doubled die. You can have a doubled die with Machine Doubling, but the Machine Doubling never creates a doubled die coin. You could own a rare car, but if it has a door ding on it, it is still a rare car, but a door ding doesn't make the any car rare. They are post factory events. (Damage to the coin/cars)

Also on the yellow arrows, you can see there the Machine Doubling is flat and showing a 90 degree angle where the metal was moved. (even the mintmarks are showing Machine Doubling)

CoopHome: Why does Machine Doubling never make a coin a doubled die? Machine Doubling is a post strike event. a doubled die comes from a die that has hub doubling on it. Machine Doubling is nor raised. a doubled die raised as it is part of the hub doubling on the die. Thus without the area being raised, it is not a doubled die. doubled dies are caused by a doubled die. Machine Doubling is caused by a loose machine.
