Point your camera at a coin and find out what it is, what condition it is in, and what it may be worth. Coinara is a coin identifier and coin value scanner for collectors, for anyone who inherited an old coin jar, and for anyone who just found something interesting in their change.
IDENTIFY ANY COIN FROM A PHOTO
Photograph the obverse and reverse and the coin scanner identifies the coin for you. A built-in detector frames the coin and warns you about blur before the shot is sent, so you get a usable photo on the first try instead of the fifth.
CHECK WHAT YOUR COIN IS WORTH
Get an estimated value for your coin, shown in the currency you choose. Values are broken down by grade, so you can see how much condition changes the number.
GRADE YOUR COIN
Run a grading report from front and back photos and get a condition assessment in plain language, with the details that drive it called out for you.
SEE THE FULL COIN PROFILE
Every identified coin opens a detail page with the specifications collectors actually check: composition, weight, diameter, thickness, designer, obverse and reverse descriptions, and Krause catalogue number.
BROWSE THE CATALOGUE
Explore coins by country and by period, and search the catalogue directly when you already know what you are looking for. Full catalogues are available for the United States, the United Kingdom and Vietnam.
BUILD YOUR COLLECTION
Save coins to your personal collection with your own notes, and keep a wishlist of the pieces you are still hunting. Your collection stays on your device.

COMMON QUESTIONS
What is my coin worth? Scan both sides and Coinara returns an estimated value by grade.
Can it identify old coins and foreign coins? Yes - scan any coin, including world and ancient pieces. Browsable catalogues currently cover the US, UK and Vietnam.
Can it read a mint mark or spot an error coin? The coin profile shows mint and variety details where the catalogue has them; rare error coins should be confirmed by a professional.
Do I need the internet? Identification runs in the cloud, so a connection is needed to scan. Your saved collection is readable offline.

A NOTE ON VALUES
Coinara gives estimates based on catalogue data and the condition it can see in your photos. It is a research tool, not a certified appraisal. For a high-value coin, confirm with a professional grading service before you buy or sell.
