I know it is possible, however not sure where to start. It would be awesome for an individual to upload an image of an unknown coin, and using Numista databases the computer determines the I.D for the coin with a probability rating as to accuracy.
Coins dated 1935 or its equivalent including No Dates.
I am currently looking for the following coins, you can view, them on my webpage: https://coinwishlist.weebly.com/
Cita: "druzhynets"Well, I think it's possible to train such a model, but it wouldn't be trivial, especially for exotic coinage.
That's an understatement. It would be a huge challenge, given how easily small differences in size/distance, lighting (color and shadows), background, and the angle could throw it off.
It should be possible with our current technology although the costs are probably the deal breaker. The FBI uses facial recognition software which I'm told is very accurate, fast and sophisticated. Their budget is several magnitudes higher than any numismatic website but who knows how cheap the technology might be 10 years down the road.
Many years ago there was a company called Compugrade which used a program to match the known wear points on a specimen coin against a database of images. They claimed such accuracy that not even the 1-100 Sheldon Scale was sufficient and were proposing a 1-1,000 scale. Imagine that, MS 900 - MS 999? Crazy eh? It never really took off and the market fell into the laps of the familiar TPGs but I wonder if a decade or more later it might be time for an enterprising start up company to take another look at the possibilities.
Old Compugrade slabs still occasionally turn up on dealer's shelves, if you are lucky enough to find one please keep it instead of sending it in to be re-slabbed. You will be preserving a fascinating piece of numismatic history and in the long term the slab may be worth more than the contents.
Non illegitimis carborundum est. Excellent advice for all coins.
Make Numismatics Great Again!

Yes, it's a challenge, but it's not impossible. It would require a lot of time, effort and resources to do that.
