Live today. The foundation of the price guide — plus your collection.

• Trade calculator

  You give / You get. Search-add any card — or pull from your vault when signed in — and see the estimated gap before you shake hands.

• Flag a bad sale

  On a card’s history row, Flag, then confirm. The row shows Flagged. The hero price only changes after a confirmed-bad remove.

• Compare cards

  Compare two cards or two treatments. Last sale, 30-day average, and sale count side by side. Works without signing in.

• Hoard, badges & ranks

  Sign in with a username, earn badges as your collection grows and you help keep sales accurate, showcase up to five on your public vault, and climb the hoard and steward boards at /leaderboards.

• Card scanner

  Scan a card from Collection or the menu. Point the camera to identify it and add it to your vault.

• Purchase price and gain/loss

  On an owned card, Set paid each on the row (or first in the Manage sheet). Paid and gain/loss sit on the row once set. Summary Paid / Gain-loss tiles only if at least one row has paid. Vault totals are a last-sale estimate. Public directory stays market-only.

• Collection import and export

  On a named collection (not All), Export CSV / Import CSV under Manage. Export is one row per vault row. Import previews adds / updates / skips, then Confirm. Quantity on a match is replaced. Nothing is deleted. Whatnot export is separate.

• Market movers

  Trends in the nav (or /trends). Public. Three lists for the last 30 days: top gainers, top losers, most traded. Tap a row to the card. No sign-in.

• Grade-level price breakdowns

  On a card page, By grade tiles under the 30/90 stats. Each grade with sales shows 30-day avg, 90-day, and sale count. Tap a tile to filter. Slabs read green vs Ungraded when the average is higher.

• Faster catalog browsing

  The catalog stays lighter as the guide grows. List pages no longer load full sale history for every card.

• Collection polish

  Mobile collection rows, faster large collections, and clearer empty-tab next steps.

• Watchlist

  Sign in, Follow on a card, then see those cards on Watchlist in nav or Account with last sale and % vs prior (or 30-day avg). No alerts.

• Real sales history on every card

  Every price is backed by actual recorded sales — not estimates. See each sale with its date, price, and grade on the card page.

• Price trends & market charts

  30 and 90-day average prices, last-sale trend indicators, and a 120-day price chart on every card detail page.

• Raw vs. graded pricing

  Filter sales history by grade so you can see what a raw copy sells for versus a graded one.
