【實用生產應用app】Coinia|最夯免費app-綠色工廠好玩App

Coinia is an app for coin collectors designed by a fellow coin collector. Coinia allows a collector to manage their United States coins issued for circulation from 1793 to present. It includes denominations of ½¢ through $20 dollar gold coins.

Features include: Interactive selectors for denomination, year, mintmark, and condition, allowing for easy input of coin information. Only valid years are displayed for specific denominations. Only valid mintmarks are displayed for denomination and year combination.

Type, variety, and composition are displayed during input. When multiple types, varieties, or compositions exist for the same denomination and year, list pickers are displayed, allowing the user to resolve the differences in type, variety, or composition variation.

With each coin entry, the user can enter a short note, detailed description, bought price, and bought date. A coin entry can also be marked as a "wanted" coin - a coin that the collector does not currently own, but wants to obtain in the future.

Users can display all of their coins in one list, or filter the database list by denomination and type. The user can also filter the list and display only coins that are marked as wanted.
