What We Do:
Authenticate Antique Advertising Signs
What does TAC mean?
TAC (pronounced “tack”) stands for The Authentication Company. Dan and Joey are experts in authenticating antique advertising signs. Items that are found to be authentic received a specific TAC number and a TAC sticker for a specific item. No items will have the same TAC number.
By marking items with our TAC sticker, it guarantees all items marked with the security holograms & serial numbers to be original items and not reproductions.

How to verify a TAC Number
All items with a TAC hologram and serial number are located in our website database. Simply type the number into the search bar and you’ll see a picture of the item. You can search by TAC # as well as keyword. For example typing Mobil into the search bar will display results with the word Mobil in the title.

The TAC Process:
A TAC employee will review your item to determine if it is authentic. Items deemed as authentic will received a TAC # which is generally placed on the front edge of an item (TAC’s discretion is used when placing the tags on items). TAC will also give the item a rating on a 1 to 10 scale which is good only for the day of the authentication. TAC uses the Matthews Grading System which can be viewed here.
TAC will also give customers a general market price estimate of the item at the time of authentication. For clients with larger collections TAC may also provide a detailed database list of their items with TAC numbers, Ratings, Price Estimates, Etc. For many collectors this is a great way to have your collection in an easily accessible file format or a printed document.
