Graded sports cards · Los Angeles, California

Every card has a room where it sells for the most. Knowing which one is the business.

EEC Vault buys graded and raw sports cards outright, submits raw material to PSA and Beckett for authentication, and places finished inventory through the four venues that set the market — Alt, Goldin, Fanatics Collect and eBay — alongside direct sales at card shows and through Instagram.

Where the inventory sells

Six channels, six different jobs

Rarity goes to auction, where competitive bidding finds the ceiling. Liquid, repeat-traded cards go to marketplaces, where the turn is faster and the comps are public. And some inventory never reaches a platform at all — it sells across a table at a show, or by direct message. Nothing is listed in one place by default.

Alt Marketplace

Collector-native platform for graded cards, pairing auctions with instant offers priced against its own market index. Settlement is quick and the buyer base is specialist rather than general.

Goldin Auction house

Established auction house for high-end cards and sports memorabilia, running weekly sales alongside marquee catalog events. This is where a genuinely rare card gets the room it needs.

Operations

How a card moves through the business

The same four stages every time, from the show floor to settled proceeds. Capital turns over rather than sitting in inventory.

Stage 1 of 4

Acquire

Private purchases, collector trades, and floor buying at national and regional shows including the National Sports Collectors Convention.

Stage 2 of 4

Authenticate

Raw cards are submitted to PSA or Beckett to be graded and encapsulated. The grade is what establishes resale value and makes the card tradeable sight-unseen.

Stage 3 of 4

Place

Each card is assigned to the venue built for it — auction where rarity needs bidders, marketplace where liquidity matters more than ceiling.

Stage 4 of 4

Settle

The platform remits proceeds after the sale clears, and capital is recycled directly into the next acquisition.
