Updated with a comment from Philip DiehlNEW YORK ( TheStreet) -- It's not Timothy Geithner's choice to order a $1 trillion coin. In fact, it may not be an option. Calls for the minting of a platinum (bullion platinum, to be precise) $1 trillion coin so as to avoid a debt ceiling clash have emerged from legitimate corners of the Web. Matt Yglesias at Slate, Joe Weisenthal at Business Insider and Nobel Prize-winning economist Paul Krugman at The New York Times are among many who have shed light on the possibility for Treasury Secretary Timothy Geithner to print a $1 trillion platinum coin, walk it over to the Federal Reserve and deposit it in the Treasury's account. The bizarre action, first noted during the 2011 debt ceiling debate by a reader of Cullen Roche's Pragmatic Capitalism finance blog, has gone viral in the past week. In interviews with two former U.S. Mint directors, TheStreet learned two differing interpretations on the U.S. code that has sparked a national conversation.
