Our Grading Science

OUR GRADING SCIENCE

At Middle East Grading Alliance, accuracy is the foundation of market confidence.

Every grade assigned represents a professional, structured and independent evaluation conducted in accordance with internationally recognized grading principles. Our methodology is designed to ensure consistency, repeatability and technical precision across all collectible categories.

1. The Principle of Accuracy

Accuracy in grading requires:

Correct authentication
Precise condition assessment
Proper variety and attribution identification
Consistent application of grading standards

A single grading decision can directly influence market value, liquidity and long-term investment potential. For that reason, MEGA applies a controlled, multi-step evaluation system.

2. Authentication Process

Before grading begins, each submitted collectible undergoes authentication to confirm originality and detect alterations.

Depending on the collectible category, authentication may include:

Microscopic surface analysis
Edge and structural examination
Print and material inspection
Metal composition analysis (where applicable)
Comparative analysis against verified reference examples

Items that fail authentication are not being graded and encapsulated.

3. Grading Standards & Scale

MEGA grading methodology is aligned with internationally recognized industry frameworks.

Coins & Numismatic Items

Graded using the internationally established 70-point numerical scale, evaluating:

Surface preservation
Strike quality
Wear and handling marks
Luster
Eye appeal

Cards (TCG, Sport, Non-Sport)

Evaluated using a structured 10-point grading scale based on:

Centering
Corners
Edges
Surface condition
Print integrity

Postal Stamps

Graded using 100-point grading scale, developed in alignment with the highest standards of the philatelic industry and recognized global practices, assessing:

Centering
Surface condition
Perforations
Color & Paper
Gum
Hinges
Cancellation
General Appearance

Chewing gum Wrappers & Inserts

Examined using a unique 10-points grading scale, which has been developed by MEGA experts based on advanced grading practices and extensive expertise in assessing wrappers attributes:

Across all categories, grading criteria are applied uniformly to ensure repeatable and consistent outcomes.

4. Multi-Stage Evaluation Process

To enhance grading accuracy, MEGA follows a structured evaluation workflow:

Step 1

Intake & Verification

Secure logging, documentation and tracking of each submission.

Step 2

Authentication

Independent verification of originality and detection of alterations or restoration.

Step 3

Primary Grading

Detailed technical assessment by professional grading specialists using magnification tools and professional lighting systems.

Step 4

Quality Control Review

Internal verification to ensure grading consistency and adherence to standards.

Step 5

Finalization & Encapsulation

Secure encapsulation within a durable, transparent protective holder.

This layered approach reduces subjectivity and supports grading reliability.

5. Consistency & Standardization

Accuracy is not only about precision – it is about consistency.

MEGA maintains:

Internal grading benchmarks
Standardized reference comparisons
Controlled grading environments
Continuous internal quality review

These measures are designed to minimize grading variance and ensure that similar items receive comparable grades over time.

6. Technology & Equipment

Modern tools support accurate human evaluation.

MEGA utilizes:

High-magnification optical equipment
Controlled lighting environments
Measurement tools for centering and alignment
Analytical equipment (where applicable)

Technology enhances observation – but final grading decisions remain professional judgments guided by structured standards.

7. Encapsulation & Preservation

Once graded, collectibles are sealed within a transparent, protective holder designed to:

Prevent tampering
Protect against environmental damage
Preserve physical integrity
Maintain long-term condition stability

Encapsulation ensures that the assigned grade remains linked to the certified item.

8. Continuous Improvement

As a modern grading company, MEGA is committed to continuously refining its grading processes.

We review methodology, monitor consistency and adapt best practices in order to:

Strengthen grading reliability
Enhance customer confidence
Support long-term market development

Accuracy is not static – it is maintained through discipline, structure and ongoing improvement.
