Slobodian 136-7: "the history of libertarianism in the United States cannot be separated from the business of selling collectible coins. The most high-profile libertarian in the country, Ron Paul, sould coins for decades, and his partner, Burton Blumert was proprietor of Camino Coins in Burlingame, California, as well as the founder of the Center for Libertarian Studies" [also involved with many other groups listed on 137]
