Condition Checklist For Buyers
Scrutinize centering, surface wear, and edge integrity, especially for higher priced listings that claim mint condition. Small print defects, corner bumps, or soft corners can have an outsized impact on final grade and future resale potential. Comparing scans or photos against population reports helps confirm whether a card is sharper or softer than typical for its assigned grade on eBay.
