Terms of use

Last updated October 11, 2026

Mint Math is a free reference tool for card collectors. By using it you agree to these terms.

Information, not advice

Prices, market figures, deal flags and the daily read are estimates built from public sold data and live listings. They can be wrong, late or incomplete. Nothing on Mint Math is financial, investment or tax advice, or a recommendation to buy, sell or grade any card. Check recent sold listings and make your own decisions.

Listings and deals

Listings shown on Mint Math belong to their sellers on eBay. We are not a party to any sale and don't handle payment, shipping, returns or authenticity. A grade shown as confirmed means eBay's listing details matched the grade we looked for; it is not a guarantee about the card. Always check the photos, the certification number and the seller before you buy.

Affiliate links

Mint Math is a member of the eBay Partner Network and may earn a commission when you buy through links on this site. This never changes the price you pay and doesn't decide which listings we show.

Your data

Your collection and other entries are stored only in your browser. You're responsible for backing them up; we can't recover them if they're lost.

Trademarks

Mint Math is independent. It is not affiliated with, endorsed by or sponsored by Nintendo, The Pokémon Company, Creatures, GAME FREAK, any sports league, players association, team or player, Topps, Panini, Upper Deck, PSA, CGC, Beckett, SGC or eBay. Names and marks belong to their owners and are used only to identify cards and services.

Fair use of the site

Please don't scrape the site or its data feeds in bulk, overload it, or try to get around its limits.

Paid features

Paid features, if offered, are billed through the provider shown at checkout, which also handles cancellations and refunds under its terms. Alerts are informational and may be delayed or missed.

No warranty

Mint Math is provided as is, without warranties of any kind. To the fullest extent the law allows, Mint Math is not liable for any loss arising from your use of the site, including decisions made on the basis of its prices or alerts.
