Muster: Challenge Coin Guide
Lifestyle
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Free for anyone who served. Log the coin, keep the story.
Every challenge coin is worth almost nothing and means almost everything. The metal is cheap. What matters is who handed it to you, and what for — and that part lives in one person's memory until it doesn't.
Muster is a field guide for the coins you were given.
LOG A COIN IN SECONDS
A name is all it takes to start. Photograph the front and the back, and the story can come later.
THE STORY IS THE POINT
Every coin gets a place to record who presented it, where, when, and why. It is the one detail no photograph carries and the first thing anyone forgets.
YOUR RACK, THE WAY IT LOOKS
Coins are shown as prints taped to the page, not rows in a spreadsheet. Sort by the date earned and it reads like the career it is.
THE CARRY COIN
Mark the one in your pocket. Coin Check puts it on screen, full size, when somebody calls one.
SHARE WITHOUT OVERSHARING
One link shows your collection and its stories. Estimated values and serial numbers never appear on it — those leave the app only in your own export.
THE FIELD MANUAL
How a coin check actually works, what damages a coin, and the words for the parts. Built in.
FREE, AND STAYING FREE
No ads. Nothing locked. No subscription. Muster is free for anyone who served, and the optional tip is exactly that — optional, and it unlocks nothing.
Your coins are yours. Delete your account from inside the app at any time and every record and photograph goes with it.
