Price Guide Methodology
How Pricing Works
The guide is built to explain where prices come from, how catalog coverage works, and why different collectible categories need different pricing logic.
Build one trusted destination to research collectible market values across categories.
This methodology page was last reviewed on 2026-03-16. Refresh timing can differ by category and source quality.
We start by building the catalog of what exists in each category so users can browse full sets, printings, games, and collectibles, not just the items currently in stock.
Each category can use different pricing sources. Cards, sports, Funko, board games, and LEGO do not all behave the same, so the guide keeps category-specific logic while presenting one clean lookup experience.
When possible, we show low, market, and high values so users can understand a range instead of treating one number like absolute truth.
Coverage By Category
Different categories are live at different maturity levels depending on source quality and catalog depth.
| Category | Primary Inputs | Status |
|---|---|---|
| Magic: The Gathering | MTG catalog + current card pricing feeds | Live now |
| Pokemon / Lorcana / Yu-Gi-Oh | Catalog data + normalized card pricing tables | Live now |
| Sports Cards | Imported catalog sets + linked market price sources | Growing |
| Board Games | Catalog imports + MSRP and publisher-aware pricing | Growing |
| Funko Pop! | Catalog imports + guide pricing fields | Live now |
| LEGO | Catalog imports + retail / market values | Live now |
Important Notes
How To Read The Prices
`Low` is the lower end of current known pricing when that source supports it. `Market` is the best current central price we have for browse and comparison. `High` represents the upper end of the pricing range when supported by the source.
Not every category will have all three values on every item. In those cases, the guide shows the best available value instead of pretending precision that does not exist.
What Comes Next
The long-term direction is stronger refresh timing, more sold-market integrations, better variant grouping, richer price history, and broader category coverage.
The guide is meant to get more useful over time as catalog quality, images, pricing sources, and history improve.
