Having a coin can be almost like accumulating a small fortune, some are worth more than their face indicates. The last word must be given to a numismatist of course, but AI can help you have a first orientationall with your phone’s camera and tools like ChatGPT or Gemini.
Chatbots equipped with Artificial Intelligence are no longer limited to offering text and interacting with the user through words, they are also suitable for analyze code, audio and even images. With the inclusion of GPT-4o, Open AI ended up offering Vision to its free users. And Google has offered a similar tool in Gemini for months; tool that can be used to analyze currencies. We tested both chatbots and they can easily become an emergency numismatist.

Gemini found a possible value for this one euro coin
The mechanics are not really a mystery, it is not for nothing that you just have to open one of the two chatbots and click on the icon in the image. Both allow it via the web, also from the application; Although on Android you need to install the Gemini APK file, Google has not yet released the app in all territories.
AIs can analyze images of coins, discover which country they belong to, the year of minting and If there is circulation that could have added value to the nominal value. To do this, they use image analysis, identification of all stamped elements and searching their training files (also on the web): according to our results, both behave reliably and correct. Gemini Advanced seemed a little more comprehensive in the task.

With current legal tender coins, there is not much to do, since their numismatic value is identical to the face value; at least as long as there are no prints with manufacturing defects. Although things change with older coins, this is where ChatGPT and Gemini are most useful. Always without your opinion being decisive: You should compare the information with a numismatic specialist.
ChatGPT and Gemini can tell you if a coin is likely to have added value, but they won’t always accept it: get advice from a numismatic expert
Identifying parts is done as follows whether you use ChatGPT or Gemini. Even if you have the paid versions of each AI (ChatGPT Plus and Gemini Advanced):
- Open the corresponding app or navigate to each chatbot’s website: here for ChatGPT and here for Gemini. You will need to log in to use the tools.
- As a new conversation will have already been opened, click on the camera icon.
- Point your phone at the room (preferably the back, although you can try both sides), take a photo and attach the file.
- Write a command so the AI knows what to do with the image. For example “I want to know if this coin has value beyond face value“.
- Send the photo with the order and the chatbots will analyze the photo and give you the information about the part as well as its value.
Never completely trust what an artificial intelligence tells you, take its opinion as a first step to remove doubts. ChatGPT and Gemini can tell you if the coin is likely to have added value in the numismatic market, but You can only confirm this with a specialist. Plus, you can get a second opinion on your mobile with apps like Coinoscope.
