Cost (Yearly Gold & Platinum Members) $35 for items up to $2499, $50 for items up to $4999 and 2% of the value of the item over $5000, each for authentication which includes tamper proof hologram, entry into the database, unique serial number, grading good for day of only, and current market value estimate.  For Silver & Non-Members costs are: $50 for items up to $2499, $100 for items up to $4999 and 4% of the value of the item over $5000.
If an item needs to be tested to confirm it's authenticity the charge will be $100.
Not all TAC items are directly issued a certificate of authenticity as some of our clients prefer to only have their items tagged with TAC specific number on a hologram. A COA from The Authentication Company LLC is only legitimate if accompanied by the exact item with matching number (both item and certificate must match). Certificates of Authenticity may be purchased after an item has been tagged however the tagged item must be presented (in person) to a TAC employee to obtain a COA.
