US dollar bills are printed with the signature of the Treasury secretary, a hallmark designed to give the world's most renowned bills gravitas and authenticity.
But Americans are worried the childish scrawl used by Jack Lew, the president Barack Obama's latest nomination for the role, risks making their greenback look like Monopoly money.
Mr Lew, who was expected to be officially nominated to the role yesterday, has a signature described as "slinky-like" and "insane". Starting off with a soft "J", the signature then descends into seven loopy scribbles.
It was first noticed in 2011 when a White House memo he had signed was circulated on the internet.
But if Mr Lew is appointed as the Treasury secretary, the signature will be seen by a far wider audience.
The White House has not yet commented on whether Mr Lew will be asked to clean up his penmanship if he does the land job.
The current Treasury secretary Timothy Geithner told National Public Radio last year that he had to work on his signature to make his name legible enough to grace the US currency.
Mr Obama's current chief of staff, Mr Lew is viewed as an expert on budgetary issues, a reputation likely to be tested as the administration gears up for another showdown with congress on the budget.
He would take the helm of the government's main agency for fiscal and economic policy as Mr Obama seeks to push through agreements on resolving the country's debt and deficits. Almost a year ago, Mr Obama promoted the 57-year-old from the director of the office of management and budget to his chief of staff, bringing him closer into the fold of the White House.
Mr Geithner is expected to step down as the Treasury secretary in the coming weeks as he seeks to move aside from politics after nearly four years at the helm. He emerged as a loyal lieutenant of Mr Obama, remaining by his side since the start of his presidency and playing a key role in fighting the recession and plotting how to avoid the fiscal cliff.
