There is something strange with the 5 euro note. What is it?

A very rich lady goes with a bag of coins (not more than 400) to the city. In the city she meets four vagabonds. She gives the first vagabond 4 coins and a quarter of the number of coins which is left in the bag. She applies the same procedure to the second, third and fourth vagabond (so division by 4 worked always). With how many coins did she leave home?

Who makes it, has no need of it.
Who buys it, has no use for it.
Who uses it can neither see nor feel it.
