Authentication Service

With over 20 years of experience, we proudly offer our world-class authentication service to you at affordable prices. Our Certificates of Authenticity and explanation letters are accepted by PayPal, eBay, and credit card companies around the world. We currently offer two levels of authentication service:

  1. Official Authentication: Detailed pictures of the item must be submitted to our e-mail address ( or our Facebook Page ( If the item is deemed authentic, the submitted pictures will be uploaded to our website. Individual Certificate of Authenticity (in PDF format) will also be issued and sent to the owner. Each Certificate of Authenticity displays a picture and detailed specifications of the item, as well as a unique QR code and web link which can be retrieved for verification purposes in the future. However, if the item is a counterfeit, an explanation letter (in PDF format) will be sent to the owner.
  2. Verbal Authentication: Detailed pictures of the item must be submitted to our e-mail address ( or our Facebook Page ( We will reply whether the item is deemed authentic or counterfeit.

We also provide an upgrade option in case your item has been authenticated verbally by us, and you later need our Certificate of Authenticity  (for authentic item) or explanation letter (for counterfeit item). However, you need to purchase an upgrade within 30 days after verbal authentication.
