Who has the jurisdiction to handle cases of counterfeiting?

The Secret Service has the jurisdiction to handle cases of counterfeiting due to its historical role in protecting the integrity of U.S. currency and investigating crimes related to counterfeiting. Established in 1865, the Secret Service was originally created to combat widespread counterfeiting that threatened the financial system of the nation. Although the agency is well-known for its protective missions, especially of the President and other high-profile figures, its financial crime investigations, including counterfeiting, remain a critical function.

The other agencies listed have distinct areas of focus: the FBI generally investigates a wide range of federal offenses including terrorism and cybercrime; the ATF is focused on firearms, explosives, and alcohol and tobacco-related law enforcement; while the DEA primarily handles drug enforcement and combating drug trafficking. Those specific focuses distinguish their roles from that of the Secret Service when it comes to counterfeiting cases.
