Iam having a lot of Japanese holo cards I want to send in to PSA; they are all totally perfect in condition, the only thing:
Due to the storage in a folder that came from the factory they all have that “curved” warped look.
Never submitted to PSA and wanted to know if anyone has experience when it comes to the grading system----will the grades be lower because of that curving?
From what I’ve heard, a light curving doesn’t influence the grade. However yours are pretty curvy, you might want to consider flattening them between to perfectly flat sheets of glass and attach some weight on top. Just leave them there a few days or weeks and you should be fine.
Does anyone have experience with this grade of curving and the PSA result? I have hundreds of cards looking like that, its a bit of a stress to flatten them, plus I don’t wanna hurt the cards
do you really think this curve will go away with this “glass-method”? Would you place the card between them with the soft sleeve or without?
Yes you should sleeve the cards for safety against scratches. @garyis2000 has been using this method successfully for years now. If you have concerns, simply leaving them in top loaders or card savers for a few weeks will also help, even if it’s not quite as effective.
Edit: just to clarify, slight curving shouldn’t affect the grade, but with a curve like in your photo, I imagine it’s hard for PSA to even put it in the case correctly.
