In this instructable, I will show you how to tell if a dollar bill is real or fake, using household materials.

Step 1: You will Need...

You will need:
A dollar bill
<p>That is so cool!</p>
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&nbsp;Bell employees. <br /> <br /> <br />
How do you know it is fake?<br />
&nbsp;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.
&nbsp;its actually not made from paper. its a blend of cotton and&nbsp;linen.
But bleaching a $1 and printing a higher denomination on the blank would fool the magnetic test.<br />
You can't bleach magnetic materials to white and have them retain magnetic properties.<br /> <br /> L<br />
Surely no one bothers counterfeiting 1$ bills? <br /> Would you consider asking shop staff to wait while you got your magnet out and tested your change...?<br /> <br /> L<br />
Do you know if the use of magnetic ink is recent?<br /> Would that test work on bills emitted some 20&nbsp;years ago?<br /> <br />
