Grading Outlook

Profit potential

How hard the money you put in works.

What it measures

Grading costs you the fee, the postage both ways, and the raw card you could have sold today. Return is what comes back divided by all of that. It levels off high up, because the gap between doubling your money and tripling it matters far less than the gap between losing it and doubling it.

A 50% return rates 57 points. A loss stops at 0 rather than going negative — one weak input should not drag a card below zero, and a card that loses money is refused outright anyway.

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

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 what it sells for at the grade you named cannot be read, this has no figure and the outlook says so rather than guessing one.
  • If what it is worth ungraded cannot be read, this has no figure and the outlook says so rather than guessing one.
  • If what grading it costs you 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.
