The Secret Service is tasked with safeguarding the payment and [[financial system]]s of the [[United States]] from a wide range of financial and cyber-based crimes. Financial investigations include counterfeit U.S. currency, bank and financial institution fraud, mail fraud, wire fraud, illicit financing operations, and major conspiracies. Cyber investigations include [[cybercrime]], network intrusions, [[identity theft]], access device fraud, credit card fraud, and intellectual property crimes. The Secret Service is also a member of the [[FBI]]'s [[Joint Terrorism Task Force]] (JTTF) which investigates and combats terrorism on a national and international scale.

The Secret Service's initial responsibility was to investigate the counterfeiting of U.S. currency, which was rampant following the [[American Civil War]]. The agency then evolved into the [[United States]]' first domestic intelligence and [[counterintelligence]] agency. Many of the agency's missions were later taken over by subsequent agencies such as the [[Federal Bureau of Investigation]] (FBI), [[Central Intelligence Agency]] (CIA), [[Drug Enforcement Administration]] (DEA), [[Bureau of Alcohol, Tobacco, Firearms, and Explosives]] (ATF), and [[IRS Criminal Investigation Division]] (IRS-CI).

The Secret Service is also tasked with investigating reports of the existence of specimens of the extremely rare [[1933 double eagle]] gold coin, as only a single example of the fourteen known survivors from this mintage year is authorized to be owned or sold.<ref>{{Cite news |date=2012-03-02 |title=1933 Double Eagle coin on display at Goldsmiths' Hall |work=BBC News |url=https://www.bbc.com/news/uk-england-london-17230477 |access-date=2023-11-07}}</ref>
