Supplied-record card analysis

Card Margin

Evaluate card resale costs from evidence you provide.

For Pokémon, Magic: The Gathering, Yu-Gi-Oh!, One Piece, Disney Lorcana and baseball, basketball, football, hockey and soccer singles, compare exact printing and grading details, inspect fresh permitted sold records, calculate CAD/USD costs, and export a report.

You supply the inventory, evidence, prices and costs. Card Margin separates raw from graded cards and reports missing evidence instead of inventing values. It models downside/base proceeds and the maximum CAD item offer that meets your stated targets. CSV exports retain assumptions, source references and exclusions so you can review the result.

The current MVP is free and requires no Card Margin account. Use it through a compatible ChatGPT/MCP client; the client's own access requirements and terms apply. MCP endpoint: collectible.airiskmanagement.ca/mcp.

All built-in examples are synthetic. Card Margin has no live marketplace feed, automatic purchasing, listing management, authenticity or grade certification, sell-through prediction, or profit guarantee. Raw cards are not valued as hypothetical graded cards. Sealed products are outside the supported scope.
