Cardholm tracks every card and sealed box you own, values it against real market prices, and shows your gains and losses the moment they move. Your whole collection — organized, priced, and honest about the numbers.
Log copies by set, condition, and grade. Cardholm keeps your cost basis and quantity so nothing gets double-counted.
Every card is priced against real market sales and refreshed daily — so the number you see is the number the market says.
See unrealized P&L against what you paid. Every change carries its sign and arrow — no guessing which way it went.
Pick a grading company and service tier, and Cardholm estimates the value at each realistic grade from real per-grade sales — then subtracts the actual fees and shipping to show what you'd net. See the break-even grade and the top-grade upside before you ever mail a card.
Track sealed boxes, ETBs, and packs beside your singles. Priced daily and folded into your total value, P&L, and allocation.
Daily gainers and losers, a watchlist with buy and sell price targets, and alerts in-app plus a daily email digest.
Add a card by photo, find anything with fuzzy search, or bulk-import a whole binder from a CSV.
Plus set-completion tracking, a shareable public showcase, realized P&L on sold cards, multi-currency (USD / EUR / GBP), and a pull-rate simulator.
Search a card, pick the set and grade, set what you paid. Add one or a whole binder.
Cardholm matches each copy — cards and sealed — to real market data and values it every day, automatically.
Track total value, daily change, and P&L over time — and know when to hold or sell.
Finally see the whole binder in one place, organized by set and grade — not scattered across sleeves and spreadsheets.
Treat cards like an asset class: real cost basis, unrealized P&L, and allocation you can actually reason about.
Watch daily movers and market trends so you know the right moment to list — and what the market will bear.
