Quick answers about how Card Inertia works.

What is Card Inertia?

Card Inertia is a trade-only meeting place for PSA Vault-to-Vault card trades. It's cards for cards — no buying or selling. Your cards never leave the PSA Vault: we don't hold cards or money and aren't a party to any trade. Card Inertia is not affiliated with PSA.

How does a trade work?

Post a listing with the cards you have and what you want, or make an offer on someone else's listing. When an offer is accepted, both traders complete the transfer in their own PSA accounts using PSA's Vault transfer tool, then mark it sent and received on Card Inertia.

What does it cost?

Trading under $1,000 is free, and we never take a cut of your trades. Trades of $1,000 or more are for the High Rollers Club, which is application-only.

What is the Founding Trader badge?

The first 500 members get a permanent Founding Trader badge.

Why isn't my new listing showing for everyone yet?

High Rollers Club members see new public listings first. Everyone else sees them up to an hour later.

What is the Hot Listings email?

A weekly email of hot listings. It's opt-in only, and you can unsubscribe anytime from the link in the email or in your account settings.

Safety tips

• Only trade through PSA Vault transfers.
• Never pay or send anything outside of PSA — Card Inertia is trade-only.
• Verify cert numbers on PSA and confirm every transfer yourself.
• If something goes wrong, report the failed trade from the trade view. An admin reviews every report.
