We found this FaceBook post from the Douglas County Sheriff's Office
In the last week, a bar in Douglas County, Minnesota, received $500 in fake $100 bills. The bills in question were passed while buying pull tabs. The Sheriff’s Office is asking anyone who works with cash to keep an eye out for fake $100 bills. If you’re not sure how to tell, there are several resources online which will help you find a fake bill. We are asking anyone who has received fake $100 bills in the past couple of months to call the Douglas County Sheriff’s Office, 320-762-8151.
Please view the picture of the fake $100 bills passed at the bar. The liberty bell on the ink well (the thing that looks like a brown pot) is color shifting and should be visible in different colors from different angles. These bills also have foreign markings on the back, left side of the bills.
