Hi all. Need some info on this type of double. Is this a double strike? Or what does a double strike look like.
Thanks to Coop and some of the other pullers I have been able to read up on Machine Doubling. Could this also be that?
And are all forms of marching doubling having the "shelf"?

THANK YOU!!

Well business strike coins are only struck once. So its not a double strike. What you are seeing is the most common doubling on coin, Machine Doubling. Not a premium coin as they are so common to find. On Machine Doubling, the die is normal, but the machine causes the doubling, just like what we see on your coin. On a doubled die, the die is doubled, thus the term doubled die.

Note the doubling. It is not on the outside edge of the coin, but in the center of the devices. But a doubled die can also show Machine Doubling. Because the machine causes the damage. But a doubled die creates all the hub doubling on the coins the same each time. (Except allowing for die wear) The answer to both of your questions, it is Machine Doubling.

Okay, so it seems that as the die itself is loosening (or the parts holding the die I should say) this causes the effect of the double image in different levels.
From a small offset as shown to much larger offsets I have seen.

Does an image of say a letter on top of itself , not offset like the image above count as "double " ... ?
I'm thinking maybe, but also thinking of other factors such as wear

The movement is called Machine Doubling. The machine caused the fresh struck devices to be altered. On a doubled die the doubling is on the die. So the term is calling it correctly as a doubled die. But if the machine causes the doubling, it is not a doubled die. But even a doubled die can show Machine Doubling. (not desired by true variety collectors) Here is an example on a doubled die:
These are all from the same big DDO-001 for that year. Note all the dates are showing hub doubling (that causes a doubled die).

But note the yellow arrows? They are showing where after the strike the machine kicked in the shins those affected areas. A grading company accepts Machine Doubling as a normal event. Doesn't consider it when the coin is graded. But to a true collector, it is as unpopular as acne on a teenager. (consider them a distraction and if used as a teaching aid, just adds confusion. So they view them as a problem coin. I know that is how I view them)

Okay Coop. I think I'm starting to get the eye for it.
Thank you again for the info and I know it's something you've said to me before. I suppose as I start to reject the obvious(To me) machine double I am still looking at variations of Machine Doubling that in am not familiar with yet.
Every bit of info help me. So again I say THANK YOU!
For your patience as well.
