Helps coin collectors and households identify coins and banknotes from a photo of each side, then see an estimated value in their own currency.

About

You point your phone at a coin or note, front then back, and the app reads the country, denomination, year and mint mark. It matches these against an index of 117,850 coins and banknotes from 358 countries and territories. Finds are added to a collection that starts greyed out and turns colour as you scan, with a running total. Where the photo and record disagree, it declines the match rather than guessing.

From the founder

Who it's for

“People with a jar of old coins, a drawer of foreign change or an inherited collection who have no idea what any of it is or whether it's worth anything, and coin collectors who want a faster way to identify and keep track of what they own.”

Why I built it

“We're two indie makers in Italy and the Netherlands. Looking up a single coin meant guessing the country, flipping through catalogue sites and comparing auction listings by hand. Buck does it from one photo: it names the coin or banknote, shows an estimated value from a catalogue of 23,000+ types, says where to sell it in your country and keeps your collection. iPhone and Android, 50 languages.”

— Emanuele Totaro, founder of Buck

FAQ

How accurate is it?

Buck reads the country, denomination, year and mint mark, then matches that against 117,850 records. When the photo and the record disagree it declines the match instead of guessing, so a blank answer means "take another shot", not "worthless".

Does it work on banknotes?

Yes. 52,375 of the records are paper, from current euros back to guilders, pesetas and marks. Same shot, same card, same collection.

Where do the values come from?

Published price guides and realised auction prices, held against the record's own metal content. Precious-metal coins are anchored to spot, so a silver dollar is never priced under what the silver alone is worth.

Will it tell me the grade?

No, and no app should. Grading is done in the hand, under a loupe, by somebody who will put their name on it. Buck shows an estimate for a coin in ordinary condition and leaves the grade to a grader.

Do I need a subscription?

Browsing the index and keeping a collection are free. Scanning needs Buck Pro, weekly or yearly, and the store shows the price for your country before you commit to anything. There is no free trial, on purpose.

What do I need to run it?

A phone with a camera, and enough light to read the coin by. Buck runs on iPhone from iOS 17 and on Android from Android 8. It is the same app on both, with the same index and the same values.
