How we price a graded card
What goes into a Cardwel offer: recent sold comps, grade and grader, how fast the card sells, and eye appeal. No mystery math.
This guide explains what a slab's certification number is, where to find it, and why sending it gets you a faster, firmer offer from Cardwel.

Every graded card comes with a certification number printed on its label. It is the card's fingerprint, and it is the fastest way to a real offer.
When you send a cert number, we can look the slab up with the grading company and confirm three things right away:
With that confirmed, we can go straight to pricing from the right sales instead of going back and forth with questions.
Look at the label at the top of the slab. The cert number is printed there, usually next to the barcode. PSA, BGS and CGC all print it on the front label. Copy it exactly as shown.
Tip: For a big lot, a quick spreadsheet with grader, cert number and card name is the fastest thing you can send. Paste it straight into our offer form.
Fake and tampered slabs exist. Verifying certs up front protects both sides. It means the offer you get is the offer you get paid, with no surprises when the cards arrive.
That is fine. Send clear photos of the front of each slab with the label readable, and we will take it from there. It just takes a little longer.
Send the cert numbers. No fees, no obligation.
