Using authentication and grading services

The authenticity and condition of collectible items like coins, stamps, or sports memorabilia can greatly affect their value. eBay sellers collectibles will often use independent authentication or grading services to get an accurate evaluation of an item’s worth.

Sellers can have their items authenticated by an independent expert before listing them, and buyers can get items evaluated before making a purchase to see if they’re getting a good deal.

What service to use

Authentication services can determine whether an item is genuine and described appropriately. Experts from these organizations can often detect counterfeits from subtle details.

Grading services determine the physical condition of an item; the system depends on the type of item graded.
