Eureka: Euro Coins

Monaco, San Marino and Vatican City strike so few coins that finding one is a small event. Eureka is a catalogue of every euro coin since 1999, from all 25 issuers. Mark the ones you own and check your change for the ones you're missing.

ALL 25 ISSUERS, FROM ANDORRA TO VATICAN CITY
Each issuer opens on its €2 coin lit in its flag's colours. Below it is every series, year and mint mark it has struck, with a picture of each coin: 600+ commemoratives and 5,500+ years and mint marks.

CHECK YOUR CHANGE
Found a coin you don't recognise? Pick the country and the value, or find it from its year and picture, and see in a few taps whether it's new to your collection.

WHO DESIGNED IT AND WHAT IT MARKS
Each coin has its own page with the reason it was struck, its designer and its release date. One tap marks it as yours.

SEE HOW FAR YOU'VE GOT
Stats show what your collection is worth at face value and how complete each issuer and denomination is. You choose whether to count one coin per design, per year or per mint.

COMPARE WITH A FRIEND
Share your collection as a link or a QR code. If your friend has Eureka, it opens on a comparison: what you both have, what only they have and what only you have, issuer by issuer.

NOTHING LEAVES YOUR PHONE
There's no account to make and nothing is tracked. The catalogue and its pictures come with the app, so it works offline and your collection stays on your device unless you send it yourself, as a backup or a link.
