Authenticity & grading

What is expert review? A reviewer checks every listing before it goes live: photos, category, and description. It checks listing quality, not authenticity. How do I check a certificate number? Look the number up on the grading company's own website and check the details match the listing photos. What is the difference between graded and raw items? A graded item has been assessed and sealed by a third-party company. A raw item has not, so you are relying on the seller and the photos.
