PSA Grading really reliable?

[gunboat82]

Just some examples of the disconnect:

VG 3: VERY GOOD

A PSA VG 3 card reveals some rounding of the corners, though not extreme. Some surface wear will be apparent, along with possible light scuffing or light scratches. Focus may be somewhat off-register and edges may exhibit noticeable wear. Much, but not all, of the card’s original gloss will be lost. Borders may be somewhat yellowed and/or discolored. A crease may be visible. Printing defects are possible. Slight stain may show on obverse and wax staining on reverse may be more prominent. Centering must be 90/10 or better on the front and back.

GOOD 2: GOOD

A PSA Good 2 card’s corners show accelerated rounding and surface wear is starting to become obvious. A good card may have scratching, scuffing, light staining, or chipping of enamel on obverse. There may be several creases. Original gloss may be completely absent. Card may show considerable discoloration. Centering must be 90/10 or better on the front and back.

FR 1.5: FAIR

A PSA Fair 1.5 card’s corners will show extreme wear, possibly affecting framing of the picture. The surface of the card will show advanced stages of wear, including scuffing, scratching, pitting, chipping and staining. The picture will possibly be quite out-of-register and the borders may have become brown and dirty. The card may have one or more heavy creases. In order to achieve a Fair grade, a card must be fully intact. Even though the card may be heavily worn, it cannot achieve this grade if it is missing solid pieces of the card as a result of a major tear, etc. This would include damage such as the removal of the back layer of the card or an entire corner. The centering must be approximately 90/10 or better on the front and back.
