Estes Park Police are warning businesses and shop owners about counterfeit bills that could be circulating after a fake $100 bill was used in the town.

Estes Park Police are urging the training of employees on how to spot a fake bill. I have never personally seen a counterfeit bill before... At least not that I am aware of anyway. If you would like to learn more about counterfeit currency, you can check out  the Secret Service site HERE for information.
