The Standards · Public Rubric

Measured.
Not estimated.

Card grading is a luxury service. Customers should know exactly how their cards will be judged before they send them in. Below is the entire Excalibur rubric: the same one we apply to every examination, every time, on camera.

Step 01 · Sub-grades

Four measurements.

Each card is examined across four independent dimensions. The final grade is the average of all four.

01 — CENTERING

Centering

How close the width of the four borders are to one another, measured precisely in millimetres.

02 — CORNERS

Corners

How many of the four corners are rounded to the perfect 3.175 mm radius.

03 — SURFACE

Surface

How much damage, if any, appears on the front and back of the card.

04 — EDGES

Edges

How much damage, if any, appears on the outside edges of the card.

Step 02 · The Scale

From Atrocious
to Prismatic.

After examination, the card receives a final grade between 1 and 10, derived from the average of the four sub-grades.
