A Buyer’s Guide to Third Party Authenticators
Share
Why Third Party Authentication Matters
Third party authenticators exist to protect both buyers and sellers. They provide unbiased expert opinions using brand knowledge, reference databases, stitching and hardware standards, and deep familiarity with production eras. Their work adds a critical layer of safety in the luxury resale world.
Some sellers do not provide Certificates of Authenticity. This does not automatically mean the item is questionable, but it does mean buyers should take an extra step. Luxury purchases require due diligence, and protecting your investment is always worth it.
You Can Authenticate Before You Buy
Many shoppers do not realize that you can authenticate a piece before purchasing it. If the seller provides clear listing photos, you can submit those images to a reputable third party authenticator and request a professional review. Experienced collectors do this regularly, especially for higher value pieces or peer to peer transactions.
What you need:
• Listing photos
• Close ups of stitching, corners, glazing, and hardware
• Heat stamp, date code, or microchip
• Any packaging or extras shown in the listing
This simple step gives you clarity and confidence before you spend a single dollar.
Understanding Authentication Pricing
Prices vary depending on which service you choose. Each authenticator has its own fee structure based on brand, item type, turnaround time, and whether you want a full certificate or a basic opinion. Some offer rush services, while others provide more affordable standard reviews.
Many buyers also wonder why some sellers charge extra for a COA. Authentication is a paid service, and every certificate costs money to obtain. When a seller includes it “for free,” that cost has simply been absorbed and built into the final price. When a seller charges separately, they are being transparent about the actual authentication fee. Both approaches are normal within the resale industry.
Choosing the level of reassurance that matches your comfort and budget is an important part of the process.
