9.5 / 10
Mint+ Condition
This card meets the criteria for a 9.5 grade across all measured
factors. Surface quality, centering, and edge condition exceed the
threshold for Mint, with one minor edge measurement preventing a
perfect 10.
Measured border offset on front and back faces. Within tolerance
for Mint+ classification.
Surface
10 / 10
Surface reconstruction detected no scratches, dents, or print
defects above measurement threshold.
Corners
9.5 / 10
All four corners measured against reference geometry. Three
corners sharp, one corner with minor rounding within Mint+
tolerance.
Edges
9 / 10
Edge uniformity measured around full card perimeter. Minor
variation on one edge — the limiting factor preventing a perfect
grade.
Why 9.5?
Grading rationale.
This card measured at the upper threshold for Mint+ across three
of four grading factors. Surface reconstruction detected no
defects. Centering is within 55/45 tolerance on both axes. Three
of four corners are geometrically sharp.
Two factors prevented a perfect 10: the bottom-left corner shows
0.18mm of rounding with trace whitening, and the left edge has
2.1mm of minor whitening between 38–40mm from the top. A Pristine
10 grade requires all corners and edges within 0.1mm tolerance
with no whitening. This card falls one tier below that threshold.

Corner analysis.
Each corner of both faces is measured against reference geometry at 80
pixels per millimetre. Any rounding, whitening, or damage is
quantified and included in the corner sub-score. This card scored
9.5/10 — seven corners are within Mint tolerance, one shows minor wear
flagged below.

Edge analysis.
Each edge of both faces is measured across its full length for
uniformity, chipping, and surface breaks. The edge sub-score of 9/10
was limited by minor variation on the front-left edge — all other
edges are within Mint tolerance.

Surface analysis.
Photometric stereo reconstruction captured the full surface of the
card at microscopic resolution across both faces. The surface
sub-score is 10/10 — no scratches, dents, or print defects detected
above measurement threshold.

Centering measurement.
Border offsets measured at three points along each side of both faces
— 24 measurements total. A single midpoint reading would mask print
skew and warp; three points along each side reveal whether the border
runs parallel to the cut edge or tilts diagonally across the card.

Shape and flatness.
Card shape measured in three dimensions and compared against a
perfectly flat reference plane. Warp, bow, and twist are quantified.
