How to Sell a Sports Card Collection
Written by Brandon Lawrence, founder of The Card Breaks, a Minnesota-based sports and trading card business.
Whether it's a handful of key cards or a collection built over years, here's how to get the most useful offer the first time you reach out.
Before you submit
- Photograph your key cards front and back, in good light.
- Note anything you already know about condition, such as visible wear or a prior grading submission.
- Have a rough count ready — an exact number isn't necessary, but a range helps.
- Decide what you're looking for: cash, store credit, or a trade. Store credit offers are typically higher than cash offers.
How it works
- Send details. Describe what you have and add photos of the key cards through the Sell or Trade form.
- We review. We check condition, recent sold comps, and demand.
- Get an offer. Cash, store credit, or trade, with no pressure to accept. We reply within 2 business days.
- Meet or ship. Twin Cities collectors can meet in a public place. Everyone else ships with tracking.
What to expect
Submitting a collection does not guarantee an offer. Offers are based on condition, authenticity, market demand, recent comparable sales, and expected resale costs, and are valid for 7 days unless stated otherwise. A final offer is confirmed after we inspect the cards in person or after they arrive. You must own what you submit — we do not buy stolen or counterfeit items.
For a shipped collection, you cover shipping to us unless we agree otherwise; if you decline a final offer, we return the cards at our cost. Store credit has no cash value and does not expire.
