Step 1
Submit your item
Add your item to the platform with photos, a description, and any provenance you have — letters, certificates, photographs with the signee, or purchase receipts.
🔎
Step 2
Choose your verification type
Select how you want the item assessed. This determines which specialists are available to you and what they charge. Five options are available — from a quick remote review to a full in-person call out.
Each verifier sets their own turnaround time, displayed on their profile when you select them.
🧑💼
Step 3
Pick a specialist & agree the fee
You’re shown a list of approved specialists in your item’s category, filtered by your chosen verification type. Each profile shows their fee, turnaround time, and credentials.
You choose whether to cover the verification fee yourself, split it 50/50, or pass it to the buyer. The full cost breakdown is shown before you confirm.
📜
Step 4
Verification & certificate issued
The specialist examines your item according to the agreed method. If it passes, a digital Certificate of Authenticity is issued and permanently attached to the item on the platform.
If it doesn’t pass, the item is returned. It will never be listed.
🛍️
Step 5
Listed & sold securely
Your verified item goes live with the CoA visible to every buyer. When it sells, payment is held in escrow until delivery is confirmed. Cardarooz takes a 5% commission on the sale price only. The CoA transfers to the new owner automatically.

🛡️
The digital CoA travels with the item forever
Every verified item carries a unique digital certificate. It records who verified it, how, and when. It’s publicly scannable and permanently attached — if the item is ever resold, the CoA transfers to the new owner, building a verified ownership chain over time.
Common questions
How long does verification take?
It depends on the specialist you choose and the verification type. Each verifier publishes their current turnaround time on their profile. Remote views and provenance checks are typically faster than shipping or in-person methods. You’ll see the estimated time before you confirm.
How much does verification cost?
Each specialist sets their own fee, which varies by verification type and item category. Cardarooz adds 20% on top of the verification fee only — this is the only charge at the verification stage. The total is shown clearly before you select a verifier. You also choose whether to pay it yourself, split it with the buyer, or pass the full cost to the buyer.
What does Cardarooz charge on the sale?
5% of the final sale price only. Nothing else is deducted at the point of sale. The verification fee is a separate transaction that has already been settled before the item is listed.
Who are the verifiers?
Independent specialists approved by Cardarooz. They have backgrounds in sports memorabilia authentication, auction houses, and category-specific collecting. Each covers specific specialisms — football, combat sports, motorsport, music, and more. You choose who you trust with your item.
What if my item fails verification?
It is returned to you. We never list items that don’t pass. The specialist will provide a clear explanation of their findings. The verification fee is still payable — the specialist has done the work regardless of outcome.
Can I get something verified without selling it?
Yes. You can request verification on any item you own through your account at any time, whether or not you intend to list it for sale. The same fee structure applies.
Can I become a verifier on Cardarooz?
Yes — if you have expertise in sports or entertainment memorabilia authentication, you can apply to join the verifier network. You set your own fees and turnaround times. Applications are reviewed by the Cardarooz team.
