Identify postage stamps and estimate their value from a photo. Stamp ID & Value Scanner gives collectors a likely match, confidence guidance, visible condition details, and a practical market-value range in seconds. Take a clear photo or choose one from your library. The app analyzes visible features such as country, issue period, denomination, design, color, and condition to suggest a likely stamp or series. What you get: • A suggested country, issue period, and denomination • Confidence guidance and visual cues behind the match • A condition overview, including perforations, cancellation, and gum • An estimated value range with market context and basis • Similar-looking stamps to compare • Scan history to save and revisit discoveries Built for collectors, hobbyists, and people evaluating inherited collections, it supports classic, vintage, and modern postage stamps. Results are guidance—not a catalog appraisal or auction-house valuation. Clear, well-lit photos of the complete stamp, including perforations, produce better results.
