Mechanical Doubling. 1 1

[Lost in the Groove]

Im sure this is overly asked on here.  But, being as new as I am and trying to learn I just thought I would ask to confirm what I am thinking.  Are these 2 pictures that I have taken today off of a microscope screen very good examples of what is called mechanical doubling?  Sorry if this is taking up space and people are tired of answering questions like this.  Thanks for everyone's time.

Yes.  Both images are mechanical doubling (aka machine doubling, AKA strike doubling).  The flat, shelf-like doubling without any indication of split serifs is a dead giveaway.

Ok.  Thank you very much for the info.  Have a great day!

   Yes, this is an example of mechanical or strike doubling, which is caused by the die being loose in the press. The secondary image is much shallower than the primary image.  It can be interesting when there is this much spread between the two images, but such coins are not valuable and are not attributed by grading services.

Yes, both examples of the common mechanical doubling.
