Hi,
   I am curious to the groups thoughts on OC and other qualifiers.  For example:

  The card on the left is a PSA 7 with a (OC) qualifier.  The right is a PSA 6.  I agree with the sentiment of buy the card not the holder (I like the PSA 6 more than the 7 personally), but I am curious as to what would be the no qualifier equivalent?  I.e. typically a PSA X is generally has the same value as a PSA 7 (OC)?
  Or is this the case where it just depends on the specific circumstances?
Thanks,
Jim
