How We Grade

Overview

SGA uses a standardized grading system designed specifically for collectible stickers and adhesive media.

Evaluation Criteria

Each submission is evaluated across four core categories:

• Surface Condition — scratches, wear, defects

• Print Quality & Color Integrity — clarity, saturation, and consistency

• Centering & Cut Accuracy — alignment and edge precision

• Adhesive & Backing Condition — structural integrity and preservation

Final Grade

Each category contributes to a final composite SGA grade, ensuring consistency and repeatability across all evaluations.

Registry Documentation

All graded items are documented within the official SGA registry, providing a permanent record of condition, classification, and population data.
