Trading cards: graded cards as NFTs

Courtyard and Collector Crypt in one place: floors, volume and owners, filters by game, grader, grade and year, the floor of every grade, and your own cards valued by grade.

What it is

Some NFTs stand for one real, graded trading card: Pokémon, baseball, basketball, One Piece and more. The issuer keeps the card in its vault, and the token is how you own and trade it. To hold the card itself, you redeem the token with the issuer, who ships it to you.

Trading cards puts the issuers FloorFeed follows side by side (Courtyard on Polygon, Collector Crypt on Solana), lets you browse their cheapest listings by game, grader, grade and year, shows the floor of every grade, and values the cards in your wallets by their grade. FloorFeed doesn't hold cards, tokens or money: buying, offers and listing are the collection and NFT pages' own flows, signed in your wallet.

Where to find it

Markets → Trading cards › at the top right of Markets (phones and computers).

On a computer: More → Trading cards in the bar across the top.

Your NFTs: a Trading cards line, when you hold any, opens it.

Step by step

  1. Open Trading cards

    On Markets, press Trading cards › at the top. Each issuer's collection shows its Floor, 24h volume, 24h sales, Owners and its Last sales, with each sale's grade when FloorFeed knows it.

  2. Filter by game, grader, grade or year

    Under Browse, pick the collection (Courtyard or Collector Crypt), then press the chips: Game (Pokémon, Baseball…), Grader (PSA, CGC, BGS…), Grade and Year. Each chip says how many listed cards it would show; press it again to clear it.

  3. Read the floor by grade

    Floor by grade lists the cheapest listing of each grade, best grade first, with how many are listed. Press a grade to see only those cards.

    Floor by grade: PSA 10, CGC 9.5, PSA 9 with their floors

  4. Open a card to buy or offer

    Press a card to open its page, check its grade and details, and buy it or make an offer there. Buy, offer or list › on a collection opens its page, with Buy floor, Make an offer and listing. Courtyard's prices are in USDC.e on Polygon: if you're short, Swap & continue gets it for you.

  5. See your own cards

    Signed in, Your cards lists the tokenized cards in your wallets with their grade, each worth the cheapest listing of the same grade where FloorFeed read one (grade floor), else the collection floor, and their total.

Options

Grades
Shown as grader and number (PSA 10, CGC 9.5, BGS 9.5); Pristine and Black Label are kept apart from a plain 10. Cards an issuer marks as ungraded (sealed product, merch) have no grade.
Games
The issuer's own category, with spellings merged (Pokemon and Pokémon are one game).

Fees and limits

Polygon (Courtyard)
Priced in USDC.e, with a little POL for gas and a one-time approval before your first buy. Any FloorFeed fee is shown on the button before you sign.
Solana (Collector Crypt)
Priced in SOL, bought through the collection page as any Solana NFT. Any FloorFeed fee is shown on the button before you sign.
Redeeming
Shipping and any redemption fee are the issuer's, paid on their site. FloorFeed isn't part of it.
  • Grades, games and years come from each issuer's details on the token. A card whose issuer doesn't say them can't be filtered, and is valued at the collection floor.
  • Browsing and floors by grade read each collection's 200 cheapest listings. A grade whose cheapest copy costs more than those shows no floor here.
  • Price alerts work on a whole collection (its page → Floor alerts), not on one grade.
  • Only issuers whose collections FloorFeed has checked against their own published addresses are listed: Courtyard and Collector Crypt for now.

Troubleshooting

It says Reading these cards' grades.
The first look at a collection reads its listings' details. Give it a few seconds: the page looks again by itself.
My card shows the collection floor, not a grade floor.
No listing of its grade was among the cheapest ones read, or its issuer doesn't give its grade. The value is the collection floor until one is.
How do I get the physical card?
Redeem it on the issuer's site (courtyard.io or collectorcrypt.com). They burn or lock the token and ship the card; FloorFeed can't do it for you.

Questions

Does FloorFeed hold the cards or my money?
No. The issuer holds the card; you hold the token in your own wallet. FloorFeed shows the market and builds trades you sign yourself.
Who checks the card's condition?
The grader (PSA, CGC, BGS…) graded it, and the issuer stores and insures it. Read the issuer's terms before you buy.
Are there packs?
Not on FloorFeed. Issuers sell packs on their own sites; FloorFeed only shows and trades single cards.
