1944 P Lincoln Cent Normal PMD Or DDO?

This is an example of a 1944 with class VI doubling at the date. The extra thickness of the doubling is only seen on specific parts of the numerals like the tail of the 9 ,while other parts , like 2 o'clock on the upper curve of the 9 are of normal thickness. This is the distorted extra thickness to look for to identify a doubled die of this type. Overall extra thickness of the whole numeral or letter usually indicates a deteriorating die or circulation flattening.

I'm not seeing anything on your coin that shows the distortion of a doubled die.

Yes, circulation flattening in this case I believe.

Circulation flattening. Hadn't heard of CF. It appears my 44 is flattened in a very uniform manner both OB and REV and more consistent with a deteriorated die. Probably a combination of DD and CF. Also, I imagine CF could result in PMD that would obliterate any indication of a DDO/R. Thanks IJN, John1 and Stoneman. Learn something new every day.

Well, I'm late to this party, so I have to agree with flattening due to circulation. If there were doubling, you still see small remnants of it at the corners of the devices (at the serifs)
