In addition to numerical grades, MEGA applies widely recognized suffixes to further define key characteristics such as gum condition, hinge status, and defects status. This standardized designation system aligns MEGA-certified stamps with international philatelic conventions. It enables collectors, dealers, and institutions to confidently compare, trade, and curate MEGA-graded material within the global marketplace.
MEGA Stamp Suffixes System
Main Condition Suffixes (Status & Usage)
These suffixes indicate the general condition and usage of the stamp.
Hinge Condition Suffixes (Gum-Specific)
These suffixes focus specifically on hinge marks or gum-related handling.
Preservation & Faults Suffixes (Condition Imperfections)
These suffixes describe the degree and type of faults or imperfections present on the stamp.
Suffix Application Rules
A stamp may carry multiple suffixes to accurately describe its condition.
Order of application: Main Condition → Hinge Condition → Preservation/Faults.
Example:
NH-HH-MF → Never Hinged, heavily hinged (residual), minor faults.
Only suffixes verified by the grader should be applied.
Avoid redundant or conflicting suffixes; each must convey distinct information.
Every suffix applied must correspond to observable characteristics under magnification or professional inspection.
Suffixes enhance clarity but do not replace the numerical grade.
Suffixes must be included in certification reports, marketplace listings, and catalogs.
Enables confident comparison and global trade by providing standardized condition descriptors.
