# About CardVolume

CardVolume is an independent index of collectible trading cards: Pokémon, Magic: The Gathering, Yu-Gi-Oh!, sports cards, One Piece, Disney Lorcana and vintage non-sport cards. Each card gets one page with its exact identity, documented sales, graded population, the math behind grading decisions, and plain-language research.

## Why it exists

Card prices online are usually a single number with no explanation: an asking price, an average that mixes versions and grades, or one headline sale. We built CardVolume around a stricter rule. A price is a documented transaction of an exact version and grade, with a date and a link. When that evidence does not exist, we say “insufficient” rather than guess.

## What we will not do

-   Predict prices or call any card an investment.
-   Show asking prices as values or average across different versions.
-   Publish figures we cannot trace to a source.
-   Sell cards, take commissions on sales, or accept payment for coverage.

## How it is built

Research is gathered with AI assistance and checked against sources before an editor approves it. The rules come from our [Learn](https://cardvolume.com/learn/) guides, and every definition is in the [methodology](https://cardvolume.com/methodology/).

CardVolume is independent and not affiliated with any card publisher, grading company or marketplace. Contact: [hello@cardvolume.com](mailto:hello@cardvolume.com).
