Found a box of old stamps, or picked up a new one for your album? Point your camera at it and StampBrain tells you what it is. IDENTIFY ANY STAMP StampBrain reads the design, inscriptions, and perforations to identify the country, issue year, denomination, and series. It explains who or what is pictured and the history behind it, even when the stamp is in a language you can't read. CONDITION AND ESTIMATED VALUE See a condition read covering centering, cancellation, gum, and grade, plus an estimated value. Estimates are a helpful starting point, not a professional appraisal. BUILD YOUR COLLECTION Every scan becomes a collection record. Browse by country, year, or estimated value, add notes, and correct details whenever you know more. FOR INHERITED COLLECTIONS AND NEW COLLECTORS Get oriented quickly in an album you inherited, or catalog new finds as they arrive. STAMPBRAIN PREMIUM Premium includes 50 stamp scans every month and full collection management, billed monthly or yearly. Stamp packs are available if you need more scans.
