Picked up a card curious how to check centering
m new to one peice as a whole, found out about it and started watching the show(now 2 months later im on 670) started learning how to play the TCG aswell, (just with starter decks tho i am started to try to build one) but i picked up this card i really love and want to grade it, ive never graded a card before so looking for advice i was planning on prepping it and practicing how in going to prep, (just clean the card and edge pickup if needed) on a cheaper card first, easy pull sleeves and a semi rigid, itd be my first slab so im just looking for tips and how to find out just how off centered this card is i know its not perfect but is it within certain grading companies standards? The only defect of the card is the slight left to right off centering. Thanks in advance also any tips on the grading process are welcome.
