Using authentication and grading services

The authenticity and condition of collectible items like coins, stamps or sports memorabilia, can greatly affect their value.

eBay members selling collectibles will often use independent authentication or grading services to get an accurate evaluation of an item's worth.

Buyers can get items evaluated before making a purchase to see if they're getting a good deal, while sellers can boost buyer confidence by having items authenticated by an independent expert before listing.

What service to use

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

Grading services, on the other hand, determine the physical condition of an item and the system depends on the type of item being graded.
