How our research works.
Clear separation between education, marketplace links, and any claim that requires independent verification.
Editorial approach
GradedCoins.co explains established collecting concepts, but its articles are educational rather than personalized authentication opinions or appraisals. Wherever practical, we link to primary sources from PCGS, NGC, and other relevant organizations. We avoid representing certification populations as total rarity figures, or asking prices as sold values.
Affiliate relationships
GradedCoins.co may earn commissions from qualifying eBay transactions through the eBay Partner Network. Shop and sold-comparable links can include campaign tracking parameters. We use these links as discovery tools for independent marketplace listings. Third-party sellers control their inventory, descriptions, prices, images, fulfillment, and return terms.
Imagery and real coins
The site's editorial photos are illustrative and may not depict a real certified specimen, true grading label, or coin currently for sale. Every actual purchase should be based on the third-party seller's own photographs, certification checks, and terms.
What readers must verify
Cert numbers, holder integrity, signatures, surface appearance, market comparables, and reported population figures deserve independent checking. Use official service tools to verify certification records and consult a professional when the stakes justify it. Grades are service opinions rather than appraisals or investment endorsements.
Corrections policy
We aim to correct factual errors as identified. Grading terminology, current fees, and policies can change after publication; official primary sources should govern those decisions. This is an independent publication and does not imply endorsement by PCGS, NGC, CAC, or eBay.
