Could the answer to the U.S. economy's woes be solved with the creation of one platinum coin to the value of one trillion dollars? Well that's what pundits have offered as a comical solution to the country's debt-crisis. An online petition on Whitehouse.gov calls for signatures to "Direct the United States Mint to make a single platinum trillion dollar coin". And it's already gathered over 7,000 signatures. The idea even caught the attention of comic Stephen Colbert.
