Hub Doubling/Machine Doubling
Can have hub Doubling and machine Doubling on the same coin? I have a 1993 D cent with what appears to be just that. Machine Doubling above Lincoln's head and hub Doubling below his chin, ear and nostrel. Will post images.

Re: Hub Doubling/Machine Doubling
The marking over Lincoln's head appears to be a plating issue to me...JMO
Re: Hub Doubling/Machine Doubling
Those images were clear as a bell. Posted, they look blurry. Maybe you are right. May be a plating. Issue above Lincoln's head.
Could be that I see the images on a 42 inch tv monitor before posting then see them posted on a 6 inch phone after posting?

Re: Hub Doubling/Machine Doubling
This is a plating issue and mechanical doubling and anytime you see the part of the zinc then the plating is split. Hub doubling is more common than a doubled die from the working die since it is the hub that creates the working die. I recommend to reading the cherry pickers guide or reading Wexlers' doubled die articles on doubled dies.
I also created a video on doubled dies
