I've written a lot about repugnance and money, but never quite like this. Here's the Telegraph story on some new banknotes:
New £5 notes contain animal fat, says Bank of England, drawing anger from vegans and vegetarians

"Vegans and vegetarians have voiced outrage after it emerged the new £5 notes contain tallow, a substance made from animal fat...
...
"More than 1,700 people so far have signed a petitiondemanding that the substance is no longer used in the production of the currency. 

"The new £5 notes contain animal fat in the form of tallow. This is unacceptable to millions of vegans & vegetarians in the UK. We demand that you cease to use animal products in the production of currency that we have to use," the petition read."
