Appraise Stamp

Appraise Stamp is an AI-powered philatelic identification and grading app that helps you understand your stamp collection. Upload photos and receive detailed analysis covering country identification, era dating, RPSL/APS condition grading, perforation quality, gum condition, and collectibility assessment.

Whether you're evaluating inherited collections, vintage postage stamps, commemorative issues, or rare varieties, Appraise Stamp analyzes visible features to identify stamps, assess condition using standardized philatelic grading practices, and provide collectibility context. Each analysis includes country and denomination identification, era estimation, centering and margin assessment, perforation quality evaluation, physical defect documentation, overall condition grade (Superb to Below Average), and collectibility classification.

The app supports single stamp analysis as well as batch uploads for entire albums or collections. Users can organize stamps by album, track collection value over time, search and filter by country or grade, and understand what makes certain stamps noteworthy versus common issues.

Saved analyses can be organized into custom albums, tagged for easy reference, and shared via public links. Export tools support PDF reports suitable for insurance documentation or dealer consultations. A Value Tracker monitors your collection and highlights the highest graded stamps.
Appraise Stamp is designed for stamp collectors, philatelists, estate sellers, and anyone curious about stamps they inherit or discover.
