SlabLineage

Every collector is a seller. Letting go of the cards you don't need is how you get the grails you want — and when you sell, you should sell at today's price, not last month's.

SlabLineage is a pricing and selling platform for trading card collectors: Pokémon, One Piece, and sports.

SELL SMARTER ON EBAY Connect your eBay seller account and let SlabLineage keep your listings priced to the market. Every night, your active listings are checked against SL Consensus — our aggregated market price built from live sources across the hobby — and repriced automatically within the guardrails you set. Big moves wait for your approval. Small drifts are handled while you sleep.

WHY SPORTS AS PSA SLABS SlabLineage supports sports cards as PSA graded slabs — the segment where the sports market actually trades. It's a deliberate catalog decision: deep, accurate pricing on the slabs that move, rather than shallow coverage of everything.

Scan it. Price it. Sell it right.
