Grading Outlook

Market depth

Whether you can actually sell it once it comes back.

25% of the outlook · ×0.25

What it measures

Measured sales per month in that grader’s own market, not a guess and not an average across graders. A card can be worth a great deal in a market where nothing trades, and a graded card you cannot sell is a graded card you are holding. The gap between graders here is routinely large enough to change the answer on its own.

0.5 sales a month rates 0 points; 60 sales a month rates 100. Going from one sale a month to five changes whether you can sell at all; going from a hundred to two hundred changes nothing.

This component alone, before its weight is applied; the outlook is the four weighted together — all four on this card.

Money moves by multiplying, so a scale counting in equal steps cannot describe it.

When it has no figure

A component with no figure is an em dash and a reason, never a zero — and the card is still rated on what it does have.

  • If how often it sells cannot be read, this has no figure and the outlook says so rather than guessing one.

Which of those it was is named on the card itself, as an em dash you can click. Every reason, and whose problem each one is.

A decision aid, not financial advice. It never predicts what grade a card will get — you state the grade, and it answers at that grade. Every number on screen is an estimate you can check.
