Altworth is a collectibles platform designed to help people discover, value, buy, sell and manage their cards. It brings together a marketplace, collectible packs and tools for building and tracking a personal collection. Members can explore individual cards, including raw and graded examples, as well as sealed products, and compare prices using information about the exact printing, condition or grade. Price histories help users see how values have changed over time, while supporting data offers context for each estimate.

Collectors can record the cards they own, organize them into a collection, and follow both their value and location. Altworth supports tracking items held at home, in its vault, awaiting transfer to the vault or on their way to the collector. Users can also save cards to a wishlist and monitor their prices, or create binders and portfolios organized around sets, artwork or personal interests. For those who enjoy the surprise of discovering a new card, Altworth offers packs with a preview of potential contents.
