Boss Sports consignment portal
Sell your cards with a team that knows the market.
Estimate your payout, build your card list, see what happens next, and send a clean intake summary to Boss Sports. Approved consignments are listed as eBay auctions through the Haystack link, then tracked while the auctions run.
What you get
Built for collectors who want real exposure without managing every listing themselves.
Market positioning
We help price the card correctly.
We review condition, grade, comps and demand so each card goes live with a smart selling plan.
eBay auctions
Your cards run through public auction.
Approved cards are listed on eBay through the Haystack link so bidders can compete and the auction can run its course.
Auction tracking
Clear status from listed to paid.
The portal helps capture each eBay auction link, current status, ending price and payout notes.
What we accept
Value
Cards valued at $20 or more
Any sport, any era. Lower-value cards may work as a bulk lot if the total makes sense.
Graded
PSA, BGS and SGC slabs
Graded cards are preferred because buyers can move faster with trusted authentication.
Autographs
JSA, PSA or Beckett authentication
Signed items must be authenticated by one of these services before we list them.
How it works

Use the intake tool below to enter card details, estimated values, grading notes and contact information.
Boss Sports reviews the list.
Within 48 hours, we reply with feedback, confirm auction fit and prepare the accepted cards for eBay.
Ship approved cards.
Once approved, we confirm next steps and intake your cards for photography, Haystack listing and eBay auction launch.
Track the auction until it ends.
The eBay auction runs publicly. Once the sale clears, your payout is calculated from the final sale price minus the agreed fee.

Add the cards you want reviewed. This builds the summary in the intake tab.
Questions collectors ask
Do I have to ship before you review my cards?
No. Start with the portal summary first. We review the list and let you know which cards make sense before you ship anything.
Can I consign raw cards?
Yes, if the value is there. Graded cards are preferred, but strong raw cards can still be considered.
Where will my cards be sold?
Consignment cards will be listed as eBay auctions through the Haystack link. Once listed, the auction runs publicly until it ends.
What if I want cash today instead?
If you would rather sell outright, use our instant cash out option and we can review it as a direct purchase instead of a consignment.
