Note on the 'R' on liberty? Do you see where that area is reduced in size. On hub doubling usualy several devices will be enlarged. Just machine damage after the strike. On the good side, you are finding something that looks interesting. On the back side, you eye hasn't identified it as flatting/reducing in stead of enlarging the size of the devices. while this may look like MD on these images, it is a
DDR. Note that the devices are enlarged in size and the areas in question
are not flat looking. Also the show the color change of light to dark. (flatten areas are all the same color as there is not contour on that area. The flatness is caused by the machine damaging the coin after the strike)
Again these are hub doubled below:
