What does Gem Mint mean?
Gem Mint, abbreviated GEM MT, is a 10 — the highest grade on the scale. It means
four undamaged corners, sharp edges and a clean surface with no marks, stains or damage,
and centering better than a 60/40 split. Only very minor defects that don't detract from
the card's eye appeal are allowed.
What is the difference between Gem Mint and Mint?
A Mint 9 is allowed exactly one minor imperfection in the corners, edges or surface, and
its centering can drift to 65/35 on the front and 70/30 on the back. A Gem Mint 10 has no
imperfection worth noting and must be inside 60/40. Both look flawless at arm's length, so
the difference usually comes down to a single flaw seen under magnification — which
is why the same card is often worth several times more as a 10 than as a 9.
What does NM-MT mean on a card?
NM-MT stands for Near Mint–Mint and is an 8 on the scale, sitting between Near Mint 7
and Mint 9. It allows a few minor imperfections such as light whitening on the corners,
edges or surface, with centering inside 70/30 on the front and 75/25 on the back. It is
also written NMMT or NM/MT. NM on its own means Near Mint, which is a 7.
What does EX-MT mean?
EX-MT stands for Excellent–Mint and is a 6. It allows more noticeable damage or print
defects than an 8, with more than one area of whitening on the corners or edges, edges that
may not be sharp, and centering inside 80/20 on both the front and the back. EX on its own
is Excellent, a 5.
Does MPE use half grades?
Yes. MPE grades on a 1–10 scale with half points, so a card that is clearly stronger
than a Near Mint–Mint 8 but falls short of a Mint 9 is graded 8.5. Half grades exist
at every step of the scale and are printed on the label exactly as they are assessed. The
whole-number definitions on this page are the anchors; a half grade sits between the two
definitions either side of it.
How is card centering measured?
Centering is measured optically to 1/1000th of a millimetre. We calculate left, right, top
and bottom border percentages on both the front and the back of the card, then compare the
worst opposing pair against the tolerance for each grade. Backs are always allowed more
drift than fronts because the printing and cutting process is less precise on the reverse.
What does OC mean on an MPE label?
OC stands for Off-Center. It is applied when the centering grade comes in two or more grades
below what the rest of the card earned, which usually means a well-preserved card that was
simply cut badly at the factory. Rather than dragging the overall grade all the way down to
the centering grade, we award the grade the card's condition deserves and append OC to it,
so the label tells you honestly that centering is the outlier.
Is an MPE 10 the same as a PSA 10?
The scales line up, but no grading company can guarantee another company's number. MPE
assesses the same four categories the major grading companies do — centering, corners,
edges and surface — on the same 1–10 scale with half points, and our full
criteria are published on this page so you can check our work. Grading is still a human
judgement call everywhere, so treat a grade from any company as that company's opinion, not
a universal constant.
What happens if my card comes back Altered or Counterfeit?
Altered and Counterfeit cards are charged in full, are not added to our certification
database or population report, and are returned to you raw rather than encapsulated. We
don't put a slab around a card we believe has been recolored, trimmed, restored or faked,
because the whole point of a slab is that it vouches for the card inside it.
Do you charge for a card you can't grade?
It depends on why. A Questionable Authenticity card, where we cannot verify the card either
way, is not charged. A miscut card that physically cannot be encapsulated in an MPE slab is
not charged either, and comes back raw. Altered and Counterfeit cards are charged in full,
because verifying them is the work you paid for.
What does NG mean on a slab?
NG stands for No Grade, and it is used for cards carrying a verified in-person autograph.
The signature is the point of the card, so putting a condition number on it would be
misleading. The card is authenticated and encapsulated with an NG designation instead of a
numeric grade.
