Now this is interesting. I happened to hear a rumor about the Royal Canadian Mint commissioning a one million dollar coin a few weeks ago, and now it seems that the speculation was true.
According to the article, this almost pure gold coin will weigh in at 100 kilograms (about 220 lbs) and be the size of a large pizza, which I assume means a diameter of approximately 45 cm (18 inches). This is almost laughable, as there has never been a coin minted on the planet of this size.
Of course this is only for the people that already have it all, and I think it's a great way for the mint to continue turning a profit every year. There aren't too many crown corporations that can claim this, so it's nice to hear.
I am curious to know how many of these might be made. If I ever win more than fifty million dollars in the lottery, I might just have one of these made.
