The 25 cent coin is just beautiful, and they should have gone the other way (the c$160 coin being the transforming lenticular) because that's what people would want to buy more than anything. It's risky sending coins internationally, and I'm going to have to declare full value I think in case its lost, but it really is a beautiful piece.
I'd strongly advise people arranging a reshipper. If you were on the fence about using one, now might be the time to try one out.
On the lookout for MISB Headmaster Highbrow, Takara or Hasbro. I'm sure I could make you a sweet deal!
