The Imperium Grading Journey

Total transparency from intake to dispatch. Follow your cards through our rigorous multi-stage process with real-time alerts.

1

Arrival & Intake

Your package is opened and verified. We take intake photos and check cards against your order. You'll receive an email notification the moment we begin. Note: Unpaid cards are returned ungraded.

2

Stage 1 Grading

Initial assessment is completed by our first specialist grader. They input all data and scores into our secure system. We’ll notify you by email as soon as the grading starts.

3

Stage 2 Grading

A second, independent assessment is conducted. To ensure a non-biased, consistent result, the second grader has no knowledge of the previous scores recorded.

4

Finalisation

Our Head Grader reviews both reports for accuracy and confirms the final grade. You will receive an email once your order successfully passes through this final evaluation.

5

Label Production

Your chosen label (Standard, Retro, Set, or Art) is printed, quality checked, and prepared for the final encapsulation phase.

6

Encapsulation

The card is ultrasonically sealed in our premium, UK-manufactured slab—engineered for clarity and protection.

7

Final Quality Check

A final inspection of the finished slab ensures it meets the "Imperium Standard" before it leaves our facility.

8

Dispatch

Slabs are securely boxed and postage labels created. You'll receive a final email with tracking information and an expected delivery date.
