Probably Stolen Inspection Cheat Sheet: How to Spot Fakes

Every counterfeit tell in Probably Stolen: Hemingway cigarettes, food stamps, Immunivax serials and recalled batches, Ribwiches and water, plus how the Counterfeit Check works.

Spoiler-freeUpdated Sourced from a published guide to the in-game manuals

Quick answer

Drag the Magnifying Glass onto an item, compare it with its manual, tick the fault in the Counterfeit Check panel, then press Confront. One real fault is enough, and the seller drops the price. A wrong accusation costs reputation and the customer may leave.

The Fake Checker tests Immunivax serials, food stamps and water labels as you type.

How the Counterfeit Check works

  1. Drag the Magnifying Glass onto the item, from the counter or your inventory.
  2. Hold the mouse button and drag slowly to examine it. Use the handle to move the lens.
  3. Open the item's manual with right-click, then Read.
  4. Tick the matching reason in the Counterfeit Check panel.
  5. Press Confront.

A correct call lowers the price. A wrong one costs reputation, and the client may leave. If you find nothing, buy at the asking price. The tooltip tells you which items can be inspected.

Immunivax Injector

PartWhat to check

LabelMissing means fake; check spelling, company, product name and font
Serial numberSeven digits, from 1250000 to 4559999
Recalled batchesFirst three digits 250, 251, 301, 355, 385, 386 or 421 are unusable
BodyVisible cracks mean unusable; compare the main colors

Ribwich

The appraisal guide lists every Ribwich rule. In short, check the production date, the facility number (01 to 35), the Davre logo, the sticker on second-run items, and that a Deluxe has both a sesame bun and extra pickles.

Water

Water is fake when its purity doesn't match its label. Use a Water Testing Strip, because Ghostwater looks like better water and only a test catches it. Rustwater and Gutterflow give themselves away by color.

Customers buying in bulk may test what you sell them. See the water guide for every grade.
