I'm in the US. I got a counterfeit $5 bill from Taco Bell as change. It looked like it was made as a joke by a kid with an inkjet printer, but it sure fooled the Taco Bell employees.

How do you know it is fake?
 MICR has been around for about 30 years. Lemonie is right, why bother. The dollar is probably only worth $.15. The paper it's made from is worth more.
 its actually not made from paper. its a blend of cotton and linen.

But bleaching a $1 and printing a higher denomination on the blank would fool the magnetic test.
You can't bleach magnetic materials to white and have them retain magnetic properties.

Surely no one bothers counterfeiting 1$ bills?
Would you consider asking shop staff to wait while you got your magnet out and tested your change...?

Do you know if the use of magnetic ink is recent?
Would that test work on bills emitted some 20 years ago?
