Ask a member of your audience to take a dollar bill out of their wallet and fold it as shown to hide the corner numbers.

Step 3: How Its Done

There are two ways to read this portion of the bill to learn the numbers in the corners. the first letter in the serial number corresponds to the number in the corners and also the letter in the circle on the left side of the bill.

A=1 B=2 C=3.....

Step 4: How to Work It.

I always notice these numbers, I am a coin/ currency collector. Some rare notes have stars instead of a letter in the end of the code, those are called star notes. They're very rare. You can Google them up if you want, they're really interesting.

ya, i used to have a bunch of star notes. but when i found out they were out of norm. they r allready gone :-( . they can be worth up to 300$ more w a star i heard on the history channel...

They are. What did you mean by "out of norm."?

out of the normal, or different lol

its alot easier to tell the number by the big letter in the circle/seal on the left side of the bill. every bill made before they started making the colored money has that circle/seal with a letter in it, which is the same as the one in the serial number, and the number of letter in the alphabet in the 4 corners.
