That is machine doubling, not a doubled die. Notice how it cuts into the devices. The obverse shows a die crack, not a rim cud. A cud would show more vertical displacement. 1971 was notorious for having machine doubling as well. Keep up the hunt!
The crack doesn't quite make it from rim to rim so it isn't a retained cud either, correct non cents?
You can see the "cutting in" effect best on the A. It is machine doubling, which was common on the reverse that year. As for the die crack, I am not an expert on the correct terminology regarding cracks connected to the rim, etc. Retained cuds show vertical displacement, but this appears to be a minor crack, which may have later developed into a retained cud and then a cud. Keep up the hunt!
Looks slightly misaligned on the obverse, Tony. Not too sure. There is some die deterioration as well that I am seeing.
Oh, yeah this cent is junk, but the steps and the upward features on the obverse is what caught my eye. I just need to know what to call it?
