But the Treasury Department said earlier this year that these alternative options would not be feasible.
"Neither the Treasury Department nor the Federal Reserve believes that the law can or should be used to facilitate the production of platinum coins for the purpose of avoiding an increase in the debt limit," Treasury spokesman Anthony Coley said in an email.
At the time, White House press secretary Jay Carney said there were only two options for dealing with the debt limit: "Congress can pay its bills or it can fail to act and put the nation into default."
"The president and the American people won’t tolerate Congressional Republicans holding the American economy hostage again simply so they can force disastrous cuts to Medicare and other programs the middle class depend on while protecting the wealthy," Carney said. "Congress needs to do its job.”
On Saturday, Obama reiterated in his weekly address he would "not negotiate over Congress’ responsibility to pay the bills it has already racked up."
"Failure to meet this responsibility would be far more dangerous than a government shutdown – it would be an economic shutdown, with impacts not just here, but around the world," Obama said.
Lawmakers must strike a deal to raise the debt ceiling before Oct. 17, according to the Treasury Department.
