The standard for verified trades.
C3 Card Exchange operates from Texas, the center of the nation, as the trusted middle point for collectible trades and purchases between collectors anywhere in the U.S. Trade item for item, buy with cash, or do both: each side ships to our Texas desk, where every item is authenticated and verified and the deal is confirmed by phone before anything ships out.
Nothing ships unverified.
C3 stands in the middle of every trade and purchase so neither side has to trust a stranger. Here's how a deal moves through us.
Make the deal
Agree on a trade, a cash purchase, or a mix of both. If cash is involved, the buyer pays now and the seller's share is held in the seller's own Stripe account.
We confirm by phone
We call both sides to confirm the mailing address, every item and the terms. Calls are recorded for both parties' protection.
We authenticate
Each side ships to our Texas desk. We inspect, photograph and verify every item, including slab certificate numbers.
Delivered, then paid
Verified items go to their new owners with tracking. The seller is paid when tracking confirms delivery. Anything that fails goes back, and the buyer is refunded.
No fakes. No ghosts.
Fakes and no-show traders are why collectors stop dealing by mail. C3 is built to stop both.
Every item checked in Texas
Every trade and purchase goes through our check-in desk, and we call both parties to confirm each shipment before it's sent on.
Slabs verified
Graded items need a valid certificate number, which we check with the grading company. Raw items are checked for print, texture and condition.
Money we hold
Payments go straight into the seller's own Stripe account and are released only after authentication and confirmed delivery. Our fees come out up front.

The middle of the map. The standard for every deal.

FAQ
What does C3 do?
C3 is the checkpoint that collectible trades and purchases run through. Both sides of a deal ship to our Texas desk, we verify every item to the same standard and confirm the deal by phone, then we ship each item to its new owner. Start a verified deal.
Why Texas?
Texas sits at the center of the nation, a fair middle point between collectors on either coast. One central checkpoint means every deal is held to the same standard, wherever the two sides live.
When does the seller get paid?
C3 never holds the money. The buyer pays when the deal is agreed, our fees come out right away, and the seller's share goes into the seller's own Stripe account. It's released when the item has been authenticated and carrier tracking confirms delivery. If an item fails, the buyer is refunded in full.
What do you authenticate?
Collectibles only: trading cards of every kind, including Pokémon, sports, Magic, Yu-Gi-Oh! and One Piece, plus sealed product, comics, coins, toys and other collectibles, raw or graded. We don't handle other merchandise.
Can I trade and pay cash in the same deal?
Yes. Trade item for item, buy with cash, or combine both to even out a trade. Cash added to a trade is handled like a purchase: the member receiving it pays the commission for their plan, and the member paying it pays the 3% buyer protection fee.
How do you stop fakes?
We inspect and photograph every item at check-in and verify graded items' certificate numbers with the grading company. Anything that doesn't pass goes back to its owner. We also call both parties on every shipment to confirm the address and the items, and those calls are recorded.
