A virtual collecting game

A little discovery.
A place for every find.

Find a coin. Take a closer look. Build a binder of your best discoveries.

Preparing the catalogue and your local collection…

A collection that stays close to home.

Progress is saved in this browser on this device. Browser cleanup, private browsing, a different device, or a changed site address can make it unavailable. Keep private backups for anything you want to keep. No accounts, cloud saves, tracking or real-money purchases.

All coins are virtual. The game does not track physical ownership. Fictional credits and game conditions carry no cash value or professional grade.

Private backups include your wallet and history. A collection snapshot contains only the selected binder designs, conditions and mint marks.

A closer look

Original symbolic art. Game condition is not a coin grade.

Your local collection

Saves & privacy

Local progress stays on this device. Download a backup to keep another copy.

Private backups

Includes your wallet, pending coins and play history. Keep this file private. Import replaces your local collection; rewards are never merged.

Recovery

Restore the last good stored copy, or export the original data for safekeeping. Unknown or damaged saves are never reset automatically.

Collection snapshot

A separate, sanitized file containing only the albums you select, a fixed collector name, designs, conditions and mint marks. Downloading does not publish it.

Include albums

Open the collection showcase ↗ and import your snapshot there. It starts with a labeled sample; there is no automatic sync or upload.

Start a fresh collection

Reset replaces current progress with a fresh desk. A valid previous save may remain as the last good recovery copy until your next change. Download a private backup for safekeeping; clear this site’s browser data to remove local copies.

Browser storage can be cleared or refused. There is no server copy, account recovery, or guaranteed permanent storage. Long play histories have a 16 MiB save limit; an oversized change is refused while the previous saved collection remains intact.
