Here is the facts as I see them:
1.) It is true there are people who support the concept of a unified NA currency, but this is purely hypothetical. The support for a single currency comes from scholars, and not from any government bodies.
2.)Canada’s dollar is doing quite well right now, and Canada’s economy is in an upswing, while we know the US is facing some signs of a downturn, from Canada’s perspective this would not be a good time to unify their currency with the US, or Mexico.
3.) Three governments would have to approve this first in concept, then create a centralized bank, and then in design. I can assure you that this has not been in the news anywhere in Canada, and I am sure that it has not been on the news in the US or Mexico.
4.) The website Hal says had been put up after his story had leaked, has actually been around since 2000, although the internet archive does not have the coins page archived on there earlier than 2007-09-10 (today) as shown by the following URL:

5.) Daniel Carr designs coins, and fantasy coins so there is no reason for Daniel Carr to claim that these are his design, and that these are fantasy coins and many more reasons to believe him. In fact, if you look on the left side of the globe on the back (eagle on face), you can see Daniel Carr’s logo on Hal’s coin:

6.) The design of these coins would be considered too American to be a multinational coinage. The design is very American, and neither Mexico nor Canada would accept the iconography of that design. Just ask a Canadian if they would accept an American style liberty shield/liberty lady, stars, troy oz (Canada is Metric) or especially an eagle on coinage which is supposed to be for all three countries. All those images are very American, and are associated with the US, not Canada nor Mexico, a design for a NA coin would need to be either very generic, or very multinational to be accepted by Canada (some Canadians are quite anti-Amercian, and many would feel this coinage is an affront to Canadian sovereignty). Also why would it be the Denver mint producing the coin? Would not Canada, or Mexico have a say in where the coinage is minted?
7.) Hal Turner is a raving mad anti-semitic conspiracy theorist. He cites and anonymous treasury agent. If the person who sent this to him is anonymous, then how does he know that the “agent” is actually an agent, and not someone who thought it might be fun to pull his chain!
