Almost 
While the collision worked, it became far too intensive for use on mobile and just caused it too crash. I swapped to your coin and used the default collisions and it is working almost perfect. The only slight issue I am having is it is rolling too well, more like a tyre than a coin. I need to try and get a bit more randomness in the balance and then it will be perfect. It’s working well though and well on to getting the prototype for my game ready
