Collectors who own graded cards (slabs) and want to know what their collection is really worth: from people with a handful of PSA 10s to serious collectors with hundreds of slabs. Also collectors deciding whether to grade raw cards, and anyone who wants their collection documented for insurance.
Every value is tied to the real sales behind it. Slabline shows a card's price at every grade (PSA, BGS, SGC and CGC) along with the dated recorded sales it came from, so you can see why a card is worth what it's worth. Then it goes beyond a price tracker: it manages your whole collection like a portfolio, predicts a raw card's grade from a photo before you pay to grade it, and scores how well your collection is protected, with insurance-ready records.
Most card apps give you one number. Slabline gives you the number, the sales behind it, and what to do next: which grader pays most for your card, whether grading a raw card is worth the fee, and whether your collection is properly insured. It covers sports cards and Pokémon/TCG across four grading companies, works on web, iPhone and Android, and you can start free without an account.
Slabline is built by Hobby Smart Case, a company of collectors that makes protection gear for card collections. We kept hearing the same two questions: "what is my collection actually worth?" and "am I protected if something happens to it?" Slabline is the software answer to both: live values from real sales, and a single score for how well your collection is protected.
