Using authentication and grading services

Whether you’re buying or selling collectible items like coins, stamps, or sports memorabilia, independent authentication or grading services can help you evaluate how much an item is 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 and the system depends on the type of item being graded.

Misrepresented items

If an expert says that an item on eBay is not accurately represented, we reserve the right to remove it. If this happens, we may refund the listing fee to the seller.

Sellers can also promote the fact that an independent expert has authenticated the item, which lets bidders know that the item has been examined by an experienced professional who has pledged to provide an unbiased opinion.
