Cachet identifies postage stamps from a photo, estimates their value, and checks what they're currently listed for on real marketplaces.
The photo is usually the reason. Retake in bright, even light with the whole stamp filling the frame — avoid glare, shadows, and angles. We show honest confidence instead of guessing.
The catalogue estimate is a guide from reference data. The live market value comes from real, linked current listings — prices change and condition matters, so always verify before buying or selling. Neither is a formal appraisal.
