What must a teller complete when suspecting counterfeit currency?

When a teller suspects counterfeit currency, it is essential for them to complete a government form. This form is crucial as it serves to document the incident formally and notify the appropriate authorities, such as the Secret Service, which is responsible for investigating counterfeit currency cases. Completing this form helps ensure that there is an official record of the counterfeit incident, which can aid in further investigations and prevention efforts.

Additionally, by completing the appropriate government form, the bank fulfills its regulatory obligations and takes a proactive approach in addressing the fraudulent activity. This step is vital for maintaining the integrity of the banking system and ensuring that counterfeit detection and reporting protocols are followed properly.
