1960 Mickey mantle print defect
 

So looking into getting a higher grade 1960 mantle 7- 7.5 . Most of them have a line of dimples running across the top of the card, just under the white border. Curious if anyone knows what caused that and if say PSA would down grade because of it. Let me know what you think. Thanks
