Procedure

How it works

  1. 01

    Pick the hat and effect

    Search the Unusual you are considering and choose its exact effect.

  2. 02

    We collect the evidence

    Steam listings for that effect, its backpack.tf price, and the Steam offer book and sales history for the item.

  3. 03

    Read the verdict

    Good Buy, Fair Price, Caution, or Insufficient Data — with every source and its age on the page.

Ground rule

This effect is not all effects.

Two hats with the same name and different effects can be worth very different amounts. briefcase.tf keeps them apart.

This effect

Listings and the backpack.tf price for the exact effect you chose. The evidence behind the verdict.

All effects

The Steam offer book and sales history, which Steam only publishes for every effect together. Context, never a substitute.

When the effect has no reliable price, the case says Insufficient Data. It never borrows another effect's price.

Findings

What we've found

1.72× On the median, the Steam price sits 1.72 times above trade value.

Buying low on Steam to gain value in keys runs the wrong way, and not by accident: systematically. briefcase.tf exists to keep you out of a bad one-off deal, not to promise profit.
