About this application

OpenNumismat is a cataloging application intended for coin collectors and numismatists to organize personal collections. The program provides structured database fields for recording details such as mint year, denomination, country, composition, acquisition date, and current market value. Users can attach multiple images to each entry, categorize items using customizable tags, and generate summary reports based on filtered criteria.

The software runs on Linux and accommodates data import and export via standard spreadsheet formats for backup or sharing purposes. Collectors can track duplicates, missing items from specific series, and historical notes within a unified interface. The system relies on local storage to maintain the privacy of cataloged items without requiring an active internet connection during routine usage.
