About Slabpricing

Slabpricing is a sold-price database for graded collectible cards, stated in dollars and troy ounces of gold. It answers one question for any card, variant and grade: what did this actually sell for. It is independent, founded in 2026, and run by one person.

What we publish

Every price is computed from completed public sales. No asking prices, and no estimates dressed as sales. Beside each figure we print how many sales produced it, the window they came from, and an Evidence Grade with four values: Confirmed, Thin, Stale, Unrecorded. The sales we rejected are listed with their reasons. A grade with 2 recorded sales shows those 2 sales and no price change, because 2 sales is not a market.

Gold is the second unit. Each dollar figure divides by the London PM gold fix to give a weight in troy ounces, and a card worth one full ounce or more is a Gold Tier slab. That threshold moves with the metal every day. We publish it every day.

The record we keep on ourselves

From launch day, every estimate we publish is scored against the next realised sale of the same card and grade. The error goes up monthly, split by how liquid the card is, and no entry is ever edited after it posts. Beside it we publish how often our own indicators refuse to compute. The first months will not flatter us. Publishing them anyway is the point.

Who runs it

One person builds the site, writes the method and answers the mail. Slabpricing takes no positions in the cards it prices, and says so publicly. It indexes physical slabs only: no fractional shares, no tokens, no vault products.

How we make money

Affiliate links on live listings, disclosed at the link. Sponsorship on long-form pages, never on the method. A subscription for deeper history and portfolio tools. Display advertising never runs on a card price page, and gold-IRA advertising is declined permanently. The sample size and the Evidence Grade are free on every page and stay free.
