Omaha, Neb. (KMTV) -- - The U.S. Secret Service has a warning for vendors and businesses around the College World Series.
Nebraska's Resident Agent in Charge for the USSS, Paul Brandenburg, says large gatherings where cash is exchanged quickly can be targeted by criminals trying to pass counterfeit bills.
The Slowdown music venue says they were able to stop a man trying to use a fake $100 bill at their outdoor event last weekend.
In just one day this week, the U.S. Secret Service received more than 30 counterfeit notes that were processed through Nebraska banks. Officials say $20 bills is the most highly counterfeited note.
"I know a lot of times especially with large venues like this money's getting passed frequently in very large amounts take the extra second. The big thing I like to say is if you have a note in your hand and it feels funny give it the extra check," Brandendburg explained.
Brandenburg says check the security strip, water marks, and color changing numbers to make sure it's real. Also an easy way to check is feel a real bill and the suspected fake at the same time to see if there's a difference.
Adrienne Losee with the Slowdown says last Saturday night she warned all the workers there could be funny money reaching the registers.
"About 20 minutes later one of my bartenders said she got an actual fake 100, so even just being alerted to a false alarm she was even just aware to be like 'oh this is fake' and takes it," Losee described. "We do try to do a training with everyone to say especially with your big bills this is what you want to look for and if you have questions just take the time. It's worth taking 30 seconds just to look at it, if it holds you up for 30 seconds it's fine, people are in line for a long time 30 seconds isn't nothing to them."
