I am half tempted to try this but they want like $1.50 by PayPal for each image you try to search. And I love the concept of artificial neural networks or expert systems, but for the coins I really need a search of the image will be of a worn coin, and it will be from a series that has a lot of others close to it, like Seleucid or Ptolemy. So I'll pay the $1.50 for the challenge and the darn thing will probably tell me, yes you have a Seleucid coin there, thanks for the money! Or is it way better than that?
