Notice the flower on your coin just stops.

Magician's coin. The chance of an error comming out like this is about 1:10,000,000

Its definatly not an error coin because the design is different to the one catalouged in numista. What would the value of the coin be? would it be worth the forgers time and effort to make?

Thank you all so much. I'm quite new to this, so any feedback is greatly appreciated.
