The Bank of England may not approve but a fistful of tenners could soon be the most sought-after currency in Britain.
Each of the five £10 notes sport their own slightly naughty message from busty model Jordan - clearly not the work of the Royal Mint.
For the Brighton star's millions of fans, the notes are likely to be worth much more than their face value and city restaurateur Sue Addis is hoping to harness that popularity for charity.
When Sue, the owner of Donatello restaurant in The Lanes, Brighton, was trying to think of ways to raise money for a breast cancer appeal, she thought of regular customer Jordan.
The celebrity, whose real name is Katie Price, popped in for a meal at the restaurant last week with her ex-boyfriend Dwight Yorke and their baby Harvey.
Sue approached the model with her idea.
Sue said: "I was at the recent launch of the Pink Dolphin Appeal to raise money for a breast clinic at the Royal Sussex County Hospital.
"They gave ten of us a £10 note and told us to go out and make as much money out of it as we could.
"I managed to persuade some people to swap my tenner for £30 and I ended up with a few hundred but I hate asking people for money so I tried to think of other ways to make some cash.
"I was thinking breasts so I thought of Jordan.
"I like Katie a lot and she comes into the restaurant all the time so I got her to sign five spanking new £10 notes with her name and a naughty message, together with some pictures of herself.
"She thought it was a very good cause. Dwight offered to help as well but we couldn't think of a breast connection to get him involved with."
The Pink Dolphin Appeal aims to raise £1.5million for a new breast cancer unit at the Royal Sussex County Hospital in Brighton.
It is the latest phase in the campaign to keep breast cancer services in the city.
Sue said: "I will accept the five best offers for the tenners and donate all the money to the appeal.
"When Jordan was signing, lots of girls were coming up to her and telling her their boyfriends loved her.
"I think these notes would make fantastic and original presents for women to buy their boyfriends."
