Spot price of a 20 cent coin is currently 23.56 cents. By my math its $35 to $41.23.
Keep in mind 5c, 10c and 20c pieces are all the same in terms of composition and weight ratio. 5c for example is 1/4 the weight of a 20c.
I did the math a while back and it was getting close. Will be interesting...
