How We Authenticate: 

To ensure an accurate authentication, we don't authenticate through photos. You must send your items to us for proper authentication. Is your collection too big to ship? Want us to come to you? We can do that! Contact us if you have a large collection and we can make arrangements to authenticate your collection wherever it is. 

 

How it Works:

1. Choose which items from your collection you would like to authenticate. 

2. Download and complete our submission form.

3. Package your items for shipment.  

4. When we receive your package, we will make sure each item received matches your submitted form information and send an email letting you know.

5. Authentication turnaround time is 14 business days.

6. After reviewing your items, TAC will send an invoice to your email address. Payment is due upon receipt of the invoice. We accept Payal, checks and money orders. Remember that TAC gold and platinum members receive a discount on authentication services.

7. TAC will affix an official TAC sticker with a number to the authenticated item(s).

8. TAC will return the items in packaging provided by the customer. However, if we find the customer packaging as insufficient to protect your items, we reserve the right to charge for correct packing materials to ensure safe delivery. (Charges vary.)
