How Grailboard works

Five things a collector does here.

  1. 01

    Your Vault

    Every card you upload lives in your Vault: slabs, raw cards, binder pages, sealed product. Add the grade, the set and the story, and it shows up in the feed for other collectors.

    The Vault screen: category and type filters, Vault Walls, and a grid of three cards with their grades.
  2. 02

    Your Holy Grail

    Pick one card as your Holy Grail: the one your collection is built around. It sits at the top of your profile, so it is the first thing anyone sees.

    A collector profile with follower counts and a Holy Grail plaque showing a PSA 10 slab.
  3. 03

    Grail of the Week

    Every week a vote opens. Nominate one of your cards, then every collector gets a single vote. When the week closes, the winner is crowned Grail of the Week and shown on every Home feed.

    The Grail of the Week vote screen with a countdown, the nominees list, and a row to nominate your own card.
  4. 04

    Vault Walls

    Group cards into Walls: a team, a set, a player, a year. A Wall is a curated showcase anyone can browse from your profile.

Two moods

Private vault, or auction catalog.

Dark is deep and matte. Light is warm cream and editorial. The cards are the hero in both; the interface frames them and never competes.

Free. No tiers. Nothing for sale.

Put your grail where collectors can see it.
