Thanks for the help, Coop. The markings do not appear to be scratches after further examination of the coin.
I took some more photos and the marks appearing in EPU are raised on the coin. The marks do not "invade" the incuse lettering, which is different than the example you displayed. I respect your opinion, but I don't see evidence of any post mint surface damage around these marks. And would gas bubbles appear as "stick" like figures?
Please see the photos and comments below for further consideration.
Thanks.

The marks in the above photo between U and N are raised--and do not invade either of the adjacent devices at all. Gas bubbles? Or could they be die chips or planchet defects?

The stick like mark at the top of the N is raised and very straight and does not invade the outline of the device. Another gas bubble manifested as a straight stick? Or could it be a planchet defect?

The stick like mark at the top of the E also is also raised, very straight and does not invade the outline of the device. Gas bubble, or possibly a planchet defect?
