02The flip

The hobby is set up backwards.Flip it.

Every marketplace makes sellers shout into the void and buyers dig through it. SlabCall starts from the other end: intent first, inventory second.

The old way

Sell into the void

  • 01List it on eBay. Pay the cut.
  • 02Post it in five Facebook groups.
  • 03Story it on Instagram. Again.
  • 04Consign it and lose the margin.
  • 05Wait. Hope. Relist.

Months of hoping the right buyer stumbles in.

The SlabCall way

Demand finds you

  • 01Post what you want to buy, sell, or trade.
  • 02Match — the network finds who's on the other side.
  • 03Deal on your terms. Off our books. No fees.

Sellers search buyers. Buyers get found. That's the flip.

03The grammar

Three verbs. That's the whole network.

Everything on SlabCall is one of three moves. Each one is structured — spec, grade, terms — so the matching engine can actually work with it.

WTBWant to Buy

Put out the call.

A card spec, a grade floor, a budget, a deadline. The strongest form is a standing buy order — a limit order for cardboard.

04Bounties · standing buy orders

Put a bounty on it.Let the market come to you.

A standing buy order is a limit order for cardboard: card spec, grade floor, budget, expiry. It works while you sleep — and when it expires, the demand data stays honest.

  • Sellers and dealers search buyers, not inventory
  • Grade floors — “any PSA 8 or better” just works
  • Expiry keeps every order live, fresh, and urgent

“Someone wants your card.”The best ping in the hobby.

Keep a collection or a trade block on SlabCall and the network watches it for you. The moment somebody posts a want that matches what you own, you hear about it — not the other way around.

  • Zero effort — your collection does the selling
  • Works even if you weren't planning to sell. That's the point
  • Instant or daily digest. Your call

06Anonymous offers

Move a grailwithout showing your hand.

Serious collections don't belong on public display. Post “I'm willing to sell” with your identity masked — SlabCall brokers the introduction only when both sides opt in. Reveal is a deliberate, mutual step. Never a default.

  • The card is visible. You are not
  • Verified behind the mask — anonymity is not anarchy
  • Walk away at any point before the reveal

07The trade engine

Trades, computed.Not begged for.

Every marketplace treats trading as an afterthought. SlabCall treats it as math: your block and your wantlist on one side, everyone else's on the other, and the engine finds the intersections — including multi-party cycles no human would spot.

  • Two-party fits first; three-way cycles as the graph grows
  • Grade floors and “also take” lists respected
  • The single feature Facebook groups can never replicate

  • Luka Dončić Prizm PSA 10
  • Joe Burrow NT RPA /99

08The demand dashboard

One reputation. Three roles.Earned, not claimed.

Star ratings are for products. Deals need to know who you are as a buyer, as a seller, and as a trader — three separate scores, built from completion events both parties confirm. The trust layer the hobby has never had.

  • Role-specific scores, not one blurry average
  • Badges are earned from confirmed deals, never self-declared
  • Anonymity never hides a bad record — the score travels with the mask
