Question from a vintage neophyte…how much does card back centering matter?

90/10 is worse than 75/25.

75/25 means that one border is 3x the width of the other side's border.
90/10 means that one border is 9x the width of the other side's border. So 75/25, while ugly centering, is much better than 90/10.

Here's a good thread:

I don't know about registry bait type cards, but I know for upper midgrade or even like PSA 7, they sometimes ignore the rules on back centering. I have a '66 Koufax that should have gotten the MC qualifier because of the back - PSA gave it a straight 6. Personally as long as the back is mostly there, I could give a flip about back centering.

Ugh! You're right, I'm the one that's off. Brain cramp on me........

If the back is going to bother you and make you think about it, don't buy it. I don't like major wax on back or poor centering back. And def. not writing or paper loss.

The back caused this beautiful Yogi to be deemed o/c, which caused me to (very happily!!) pick it up at a nice discount...
