The pedigree behind every card.
Cards get cracked, pressed, touched up, and resubmitted too often. The Hobby compiles the provenance of a card, from owners, sale, and grading to alteration and quantity pulled, so the number on the slab tells the whole truth.

The Industry's Integrity
Card grading is a snapshot. Provenance is the whole story.
What's been pulled and what remains sealed
A population report counts gradings, not cards, so regrades quietly inflate it. The Hobby maps how many distinct copies of a numbered run have actually surfaced, and estimates how many are still unpulled, so you see the true scarcity behind the print run.
Cracked & Resubmitted
Follow a single card as it moves across PSA, CGC, BGS and SGC. See when a 10 today was an 8 two grades ago, the history a fresh cert number quietly erases.
One cert, whole lineage
Enter any cert number and get the complete chain of custody (owners, sales, grades and alterations) in a single shareable history that buyers can trust.
