Each extra signer on the same piece is half price. Separate items go in one at a time, as their own items. If they turn out to be separate items, we bill each signer in full before releasing your results.

Two steps to a full COA
Send us photos. Our experts review them, and each item that passes gets its own Online Pre-Certified COA number and a public page anyone can look up. Upgrade to mail-in any time — there’s no deadline.
Mail the item in for a physical inspection. It gets a tamper-proof sticker and a physical certification card.
Only items that pass online can be mailed in. You choose which ones after you see your results.
What you get
With Mail-In Authentication, after your item passes online.
Applied to your item, carrying its own certification code.
A physical card with the same code and our lead authenticator’s signature.
Clear photos get a faster answer. A dark or blurry photo is the most common reason we ask for a retake.
Do
- The whole item, straight on. Fill the frame, edges in view.
- A close-up of the signature. Sharp enough to see the pen strokes.
- Provenance and documents, if available. A receipt, a ticket or letter, a photo of it being signed.
Avoid
- Dark rooms and flash. Use daylight from a window instead.
- Blur. Hold still, tap the signature to focus.
- Glare on the signature. Tilt the item or step away from lamps.
