WHO WE ARE

Dan Matthews and Joey Whiteside formed The Authentication Company LLC after both had discussed the idea of marking and identifying advertising antiques as a means for ensuring their originality & authenticity.  TAC (pronounced “tack”) guarantees all items marked with their security holograms & serial numbers to be original items and not reproductions.  Items that are found to be authentic received a specific TAC # for a specific item.  No items will have the same TAC #.
