This makes me mad. A few months ago some NAU conspriracists starting showing images of an Amero coin as "proof" that the North American Union was genuine. I've seen pictures of these coins on anti-NAU literature and in forums. One person I talked to face-to-face said "It's true! I've seen the coin!"
The only problem is, the coin is fake. Not only is it a fake, the coin artist fully admits to it. Daniel Carr is the artist for these coins. You can buy them on his website, http://www.dc-coin.com/. Here's a link to the Amero coin page.
I have no problem with people making fake or parody coins to promote an issue. I have a major problem, however, with people deliberately using fake evidence to prove their conspiracy.
Thanks to Reason for the tip.
