Money you forgot you had
The jar on the shelf. The coins in the car door. Point your phone at one, front then back, and Buck names it, dates it and tells you what it is likely worth.

Added to your collection
Three seconds, start to number.
No lightbox, no jeweller's scale, no reference book open on the table. The phone in your pocket and enough light to read the coin by is the whole kit.
Step 1: Point
Hold the coin flat under whatever light you have. Shoot the front, then flip it for the back: Buck reads both faces and counts them as one coin.
Step 2: Snap
Buck reads the country, the denomination, the year and the mint mark off the metal, then matches them against the index.
Step 3: Value
You get an estimate in your own currency, a range where the price guide has one, with the record it matched and the reason it is worth that. Then the coin lands in your collection.
Your index starts grey.
Every coin and banknote Buck knows is already in there, sitting in greyscale. Scan one and it turns colour, permanently, with its year, its metal and what it is worth. Nobody fills the whole page.

It is easy to make an app that tells everyone their change is treasure. Buck would rather be the one you believe the day it says two dollars.

An estimate, never an offer
A coin's worth depends on its grade, and Buck is looking at a photo. So it shows an estimate from a price guide, a range where the guide has one, with the low end honest. It is never an offer to buy.
Spendable money is worth what it spends
A circulating euro coin is legal tender at its face, so Buck will never price it below that, no matter what a price guide says.
Mint state says mint state
When the only figure available is for an uncirculated example, the card says so instead of quietly pretending your pocket change is flawless.
An unsure answer is an unsure answer
If the read is unsure, or the coin is described as gold and the record is a base-metal coin, Buck declines the match rather than showing you a number it does not believe.
Everything a coin will tell you.
Composition, weight, diameter, mintage, the design on both faces and the reason it was struck. Buck shows the facts a price is built on, alongside the price.
Paper counts too
Old guilders, pesetas, a Turner twenty. Buck reads notes with the same eye it reads metal, and files them in the same collection.
What it shows, and why it was struck
Every record carries two lines on what is actually on the coin and the reason it exists. Written once from the reference, never guessed at.
Priced where you live
Values arrive converted to your home currency, so nobody has to do sums to work out whether the thing in their hand is worth a coffee.
Mintage, metal, millimetres
Composition, weight, diameter, edge, how many were struck and how many varieties exist. The facts the price is built on.
A shelf that adds itself up
Every find lands in your collection, sorted by country, with a running total underneath. The pile in the drawer finally has a number.
What is it, and what is it worth?
The questions people arrive with, answered properly: which coins are silver, where the mint mark hides, what a grade really claims, and which dates are worth stopping for.

Which US coins are silver?
Dimes, quarters and halves dated 1964 or earlier are 90% silver. Halves from 1965 to 1970 are 40%. Nickels are only silver for three wartime years, and the mint mark tells you which.

Wheat penny value: the common ones and the key dates
Most wheat pennies guide at five cents. Six issues run from $85 to $1,200 even worn, and the 1909-S VDB is the one people fake.

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".
Money youforgot you had
It has been in that drawer the whole time. One photo tells you what it is.
