Grading and pock marks on '50s cards

[toledo_mudhen]

PSA will use a number grade of the card and then add a "qualifier" for significant issues as follow :

Typically cards with qualifiers will sell for significantly less money than a "non-qualifier" grade. I have found that most quaslifiers equate to a bout a 2 point drop in number grade except for the MC (Miscut) qualifier which tends to be a stronger hit.


Types of Qualifiers

PSA has a total of six different qualifiers that can be added to a card’s grade. You can take a deeper dive into PSA’s precise definitions of each on their site but here’s a quick hitter on the six and what they stand for:

Marks (MK) – a card that has some kind of written marking on it
Miscut (MC) – a card that has been cut incorrectly by the printer
Off Center (OC) – a card that is not well centered
Out of Focus (OF) – a card that is excessively blurry or has focal issues
Print Defect (PD) – a card with a notable factory print defect
Staining (ST) – a card with a significant stain, gum or otherwise

You should know that PSA generally has some minimum standards with these. For example, a card very slightly out of focus will probably not receive the OF designation. A card with a minute print defect may not get the PD label. Typically, the defect has to be pretty significant. That isn’t always the case, though. For example, even a card with a minimal pen mark is subject to an MK designation.
