 short_description: outputs closest coins to the input, from the coins I own
+long_description: For given image of a 2€ coin, this will output 10 coins that the model assumes
+  are the closest looking to that image. However it only outputs from coins that
+  I already have, meaning I can use this to figure out, whether I already have
+  the coin or not.
