USPHS Challenge Coins

USPHS Commissioned Corps and Its Challenge Coins

The story of the U.S. Public Health Service Commissioned Corps begins in 1798, when President John Adams signed the Act for the Relief of Sick and Disabled Seamen. This law created a network of marine hospitals to care for merchant sailors — the first organized federal health system in the United States.

By 1870, the Marine Hospital Service was centralized under a Supervising Surgeon (later called the Surgeon General), and in 1871, Dr. John Maynard Woodworth introduced a military-style structure. Physicians wore uniforms, followed ranks, and could be deployed wherever disease threatened.

In 1889, Congress formally established the Commissioned Corps, aligning its pay and rank structure with the Army and Navy. Over the decades, its mission expanded far beyond the docks: fighting epidemics, improving sanitation, conducting medical research, and protecting communities from environmental hazards.

The Public Health Service Act of 1944 transformed the Corps into a multidisciplinary force — adding nurses, engineers, scientists, and other specialists. Today, more than 6,500 officers serve as “America’s Health Responders,” deploying to natural disasters, humanitarian crises, and public health emergencies at home and abroad.

Challenge Coins: Symbols of Service and Pride

Like other U.S. uniformed services, the USPHS has embraced the tradition of challenge coins — small, custom-minted medallions that carry deep meaning. These coins are often presented to recognize exceptional service, commemorate deployments, or mark special milestones.

USPHS coins frequently feature the Corps’ core values — Leadership, Service, Integrity, Excellence — along with historic symbols such as the yellow quarantine flag, the anchor and caduceus, the globe, and the Latin motto In Officio Salutis (“In the Service of Health”).

Some designs, like the “Known the World Around” coin, weave in the Corps’ official march and symbolize its three historical phases with three stars:

1. Marine Hospital Service (1798)
2. U.S. Public Health and Marine Hospital Service (1902)
3. U.S. Public Health Service (1912)

These coins are more than keepsakes — they are tangible reminders of shared mission, sacrifice, and camaraderie. Officers often exchange them during deployments or as tokens of mutual respect, reinforcing the Corps’ identity as a tight-knit, mission-driven uniformed service.
