WASHINGTON, July 16 — On the ground in the federal bureaucracy, the machinery of American money and finance operates under a single, sprawling legal framework: Title 31 of the United States Code. Enacted on September 13, 1982, as Public Law 97-258, this title is the codified statutory backbone for how the nation handles its budget, its financial management, and the very coins and currency in citizens’ pockets. The code’s structure is divided into four distinct subtitles.
Subtitle I covers general provisions. Subtitle II lays out the budget process.
Subtitle III governs financial management. And Subtitle IV, the one most Americans might recognize at the cash register, deals with money itself. Within Subtitle IV, Chapter 51 addresses coins and currency, specifying exactly what the metal in your hand must be.
Key sections define the nation’s coinage. 31 U.S.C. § 5112 sets the denominations, specifications, and design of coin. Specific subsections address the Sacagawea dollar, the American Silver Eagle, and a 50-cent coin.
The Sacagawea dollar is codified under 31 U.S.C. § 5112(a)(1). The American Silver Eagle falls under 31 U.S.C. § 5112(e). A 50-cent coin is addressed in 31 U.S.C. § 5112(l).
The latest contents of Title 31 were updated as of Public Law 115-35, enacted on May 17, 2017.
Who Runs the Money
The title does not just define coins. It establishes clear roles for the major financial actors in the federal government: the Department of the Treasury, the Office of Management and Budget, the Government Accountability Office, and Agency Chief Financial Officers. These are the institutions that execute the budget process and manage federal finances day to day.
Chapter 39 of Subtitle III provides a specific enforcement mechanism for businesses that deal with the federal government. It mandates interest penalties when federal agencies fail to pay business invoices by the due date.
For contractors waiting on payment from Washington, that chapter is the legal lever.
What to Watch
With the statutory code last updated in 2017, any legislative changes to federal financial management or coinage specifications enacted since then have not yet been codified into the published Title 31. The next public law to update the title will fold in years of potential adjustments to budget procedures, Treasury authorities, and perhaps even the design of American coinage. For now, the code remains a snapshot of the federal financial system as it stood more than nine years ago.
