Well, there's such a discussion in any forum that I went to. It is one of the reason why I didn't buy the gold coin in the first place. I didn't like the fact that it is 14k and I have to pay tax on it. But, I think RCM find the right median. If it is 24k (99.99% gold) the coin have to be (a) smaller in size or (b) higher starting price.
