I recently grabbed some Canadian PL sets and was excited to find my 2nd error, ever ( a Double Horizon). According to what I am seeing though, it would only be worth grading if it received a PL65 or higher. At 5x magnification, I noticed these obvious lines across the obverse, but used my microscope to show them to you in detail. Are they die polish lines? And if so, does this destroy the grade? P.S. Sorry for the weird color; my microscope and the cellophane don't play well together. Also, these lines are not on the cellophane... I checked multiple times.
