The questions a collector would ask first.

TCGplayer's community-sourced market data, refreshed daily. Every morning a mirror pulls the full catalog (set → rarity → card) and tags each card with prices for Near Mint, Lightly Played, Moderately Played, Heavily Played, and Damaged. The mirror records the date so every total on DisplayCase carries the same `asOfDate` stamp.

Because the pull is shared, two collectors running DisplayCase on the same morning see the same number for the same card at the same grade. Free accounts get today's snapshot; Tracker Pro adds daily auto-refresh and a rolling 60-day price history per card.

Each card you add carries one of five grade buckets: Near Mint, Lightly Played, Moderately Played, Heavily Played, or Damaged (NM / LP / MP / HP / DMG — the standard TCGplayer condition ladder). Your binder total multiplies the grade’s published factor against the PSA 10 ceiling, so a played Charizard contributes what the catalog actually says a played Charizard is worth that morning, not the best-case slab number.

If you grade a card higher than the catalog supports, the picker rejects the value. If a (card, grade) row is missing for today’s pull, DisplayCase falls back to the most recent NM row for that card and applies the grade multiplier — labelled "estimated" in the chip so you know it is a derived figure, not a fresh recording.

The AI grader reads the photos you upload and returns a single TCGplayer condition (one of NM / LP / MP / HP / DMG) with a confidence level and a short reasoning call. It focuses on centering and the kinds of wear you can see in a photo — whitening, creases, corner and edge damage.

The model is trained on real human grading feedback: every $4.49 paid request feeds the same training loop, so the estimate improves as more collectors send cards through. AI grades are always labelled as estimates — not a substitute for a real slab quote. Graded (PSA / BGS / CGC) and Professional slab pricing is on the roadmap and not yet priced.

Collectors who care about what their cards are actually worth. The product is for someone tracking a binder on a shelf — not someone listing inventory on a marketplace, and not someone looking for a price-guessing tool.

DisplayCase is a Pokemon-only tracker — pricing, catalogue, and condition grades are scoped to the Pokemon TCG catalog.

Two-stage roadmap: Now and Later. Now is Pokemon end-to-end — every modern set plus the back catalogue with clean community-sourced price data, binders, wishlist, and the daily portfolio total.

Later is AI-assisted grading and richer mobile scanning: snap a binder page, DisplayCase reads the cards, suggests a probable set, and files them under the right grade. AI-suggested grades are always labelled as suggestions, never as a substitute for a real slab. The human grading service ($4.49 per request) feeds the AI loop over time, which is why the service is paid rather than free.
