Why Choose MGC for Coin Grading?
How Does Coin Grading Work?
Your coin is carefully assessed by our expert team, encapsulated in a secure, tamper-proof slab, and assigned an official grade with a certificate label. Our slabs are designed to protect coins from damage and environmental exposure while giving them a premium, display-ready finish.
We use two grading scales depending on the type of coin:
-
Traditional coins are graded on the internationally recognised MS/PF 70 scale, which ranges from 1 (Poor) to 70 (Perfect Mint State/Proof).
-
Game and novelty coins are graded on our 1–10 scale, making it simple to understand condition at a glance.
Because coins vary in size and thickness, we use precision-fit inserts to centre and secure each piece within the slab. The label follows the same high-quality design used across all our grading services, ensuring consistency and collectability.
What If My Coin Isn’t Perfect?
We understand that many coins carry age and history. Marks, toning, scratches, or wear don’t disqualify them from grading. We’ve graded thousands of coins across all conditions and always provide a fair and professional assessment.
If you’re unsure, simply send us a photo before submitting. We’ll let you know if your coin is suitable for grading and how we expect it to perform.
