On Wednesday of this week, a business in Cannon Falls accepted a fake $100 bill. According to the Cannon Falls Police Department, the suspect was able to leave the business before the bill was verified. So what should you do if you suspect that you've been handed faux money? If the person leaves try and get a license plate number and call the local police to identify the individual.

According to fitsmallbusiness.com, the best way to spot a fake "by looking at the physical characteristics of the bill, such as ink, colors, and text." One of the first things that you can look for if you suspect the bill is fake is to see if the bill denomination on the bottom right-hand corner has the right color-shifting ink. All denominations of $5 or more have this security feature, going back to 1996. It will shift from copper to green when manipulated.

Another thing you can be looking for is red and blue fibers woven in the bill itself. The last tip to help you determine if the bill is real or not is the serial number. Here is a handy guide as I didn't know what the letters meant before the numbers on a bill. I always thought they corresponded to the state the bill was produced in. The first letter on the bill should be the same as the series which is found to the right of the presidential portrait on the front of the bill.

E = 2004
G = 2004A
I = 2006
J = 2009
L = 2009A

You can see on the bill below, which is an older series that is no longer printed.
