What you have now

A spreadsheet with pictures.

You log a card. It shows a number. Maybe the number moves. Nothing tells you whether to grade it, whether this is a good week to sell, or which two cards stand between you and a finished set. You're doing all the thinking yourself, in a notes app, at midnight.

What Legendecks does

Answers, ranked by what they're worth.

Same collection, read like a portfolio. Every morning you get a short list of moves with the dollar impact attached and the reasoning shown. Grade this. Hold that. You're two cards from the '86 set and both are cheap right now.

Goals

Tell it what you're collecting for.

Nobody collects for one reason. Some cards are the retirement fund, some are flips, some you'd never sell. Legendecks asks up front — grow value, flip for profit, complete sets, or hold long-term — and every piece of advice after that is filtered through your answer.

Name a grail and it works backwards: what it costs, what you'd have to sell to get there, and which of your cards it would hurt least to let go.

Strategic advice

A short list of moves. Every morning.

Not a feed. Not notifications. A handful of things actually worth doing today, ranked by what they're worth to you, each one showing its reasoning and how confident we are.

Grade-versus-sell math with real submission costs. Sell windows priced net of fees on every venue. Every number labelled measured or modeled, so you know which ones to lean on.

Set completion

The set you're chasing, always in view.

Pick a set and Legendecks tracks it like a progress bar — what you have, what's missing, what the gap costs at today's prices, and which of the missing cards just got cheap.

Adding is fast on purpose: choose the set once, then type card numbers or names and tap. Forty cards in a couple of minutes, not an hour of forms.

Scan & decks

Point your camera. Get a straight answer.

One photo identifies the card and reads its condition on the four things graders actually score — centering, corners, edges, surface — then caps the estimate at the weakest of them, the way a grader would. Scan a stack in one sitting and review them all at once.

Then arrange what you own into decks — rookies, PC, for sale, the '86 chase — and share one as a page that actually looks like something.

Built to be trusted with the thing you've spent years on.

Measured, or we say so

Prices come from real sold comps. Where there aren't enough sales to be confident, we tell you that instead of inventing a number.

Grader-neutral

PSA, BGS and SGC all priced side by side. We don't take a cut of your grading, so we've no reason to push one.

We're not a marketplace

We never take a cut of a sale, so the advice has nothing riding on it. Advisor, not broker.

What you paid stays yours

Cost basis and realized profit are never published, never shared, and never leave your account — even when you make a profile public.
