Ever since the United States abandoned the gold standard, the value of United States currency has been based on our nation's economic buying power and credit rather than on the amount of gold we have stored at Fort Knox. And of course, there's a conspiracy behind it all:
Bernard von NotHaus, "Monetary Architect" (and the former operator of the Royal Hawaiian Mint Company) has decided to do something about this – he has begun minting his own currency to compete with the official Federal currency. What's more, he's even filed a lawsuit against the United States Mint to force them to accept his currency as legal tender. Apparently it's legal to voluntarily use and circulate these coins and bills, as long as the phrase "Legal Tender" isn't actually printed on them.
However, NotHaus has had some trouble keeping up with inflation; the increasing cost of silver makes the coins more valuable for their silver content than their stamped base value.
The Liberty Dollar site has expressed its support for conservative political fads by issuing dollar coins promoting them. During Senator Ron Paul's Presidential run in the 2008 elections, NotHaus' outfit issued special Liberty Dollars with Ron Paul's image on the obverse. And when the so-called "teabagging" political rabble rousers worked to get attention in the media in 2009, this site issued so-called "Teabagging dollar" coins.
