TCG Price Guide is a free online resource for trading card collectors, helping users check card values, explore market trends, and organize their collections. Its catalog covers more than 4,000 trading cards, with searchable checklists spanning Pokémon, Yu-Gi-Oh!, Magic: The Gathering, sports cards, and other collectible categories. Prices are based on completed eBay sales and refined through automated analysis, focusing on actual transaction values rather than asking prices. Interactive price-history charts help collectors follow changes over time and make more informed buying and selling decisions.

The site’s collection manager lets users record cards, purchase prices and dates, condition, and notes, track their collection’s value, and share a public showcase. Currency tools support collection tracking in multiple currencies, with historical exchange rates. Curated checklists help visitors discover popular, rare, and sought-after cards, while browsing and search tools make it easier to explore the catalog. TCG Price Guide is part of Simple Price Guides and offers its collection-tracking features at no cost.
