Preserve coinage history through community
Catalogue what you own. Have the community check it.
A coin collector's album, a reference catalogue and a room full of people who know the series — in one app, free.
Coming to Android and iOS. Not yet on either store.
The album
A record of the collection, not a photo roll
Every coin gets both faces photographed and a proper record behind it — the kind of record you would keep in a ledger, held somewhere that survives a lost phone.
- Sheldon grades, P-1 to MS-70
- Provenance and acquisition notes
- Matched against the catalogue
- What you paid stays private
Verification
A second opinion from people who know the series
Post a coin and collectors vote on whether it is genuine and what it grades. Votes are weighted by the voter's track record in that era, so a verdict reflects the people who have been right before — not whoever turned up first.
- Weighted voting, not a show of hands
- 70% of the weight settles a verdict
- You cannot verify your own coin
- Every vote stays on the record
The Knowledge Base
The history behind the metal
Courses, chapters and quizzes written for collectors rather than academics — 2,600 years of Indian coinage to begin with, and the catalogue entries linked from the lessons that mention them.
- 10 courses, 48 articles
- Quizzes that mark progress
- Linked to the catalogue throughout
- Readable offline once opened
The museum
Every coin collectors chose to publish
A wall of the community's coins, filterable by country, era and metal — and the place to find out what a piece you have never seen before actually is.
- India, United States, Pakistan, Bangladesh
- Country rooms to ask in
- Nothing published without its owner choosing to
What it costs
Nothing. Not a trial and not a sample — the album, the catalogue, the museum, every course and the whole verification system are in the free version, and ads pay for it.
There is one paid extra planned: a single payment that removes those ads. It unlocks no features, and it is not available to buy yet.
Verification is an opinion, not an appraisal
A "Community verified" badge means a weighted majority of collectors who looked at the photographs believed the coin was genuine. It is not an authentication, not a certificate and not a valuation.
For anything valuable, use a professional grading service. This is said here because it is the first thing the terms say too.
