They look awesome with all the Kangaroos, now that BTC is worth more than Gold I wonder how many will move away from the metal and switch over? 
Agreed coin, it will be interesting to see if others decide to move away from metals to digital currency.
I was considering selling a gold eagle... It's a scary thought, because when parity was reached I thought I'd be buying gold, not wanting to sell it. I hope that we aren't seeing irrational exuberance given the current state of the network.
