Definition
Latin. In the civil law, false or counterfeit money. The term appears in Roman law sources, principally the Codex Justinianus (Cod. 9, 24), as the designation for currency that has been fabricated, adulterated, or passed off as genuine when it is not. It encompasses both the production of imitation coinage and the circulation of debased or fraudulent money.
Why It Matters in Research
This is a term of Roman civil law with limited independent life in common law jurisdictions. Researchers encountering it in historical sources are almost certainly working with materials that draw directly on the Corpus Juris Civilis or civilian-influenced legal traditions — canon law, admiralty, early mercantile practice, or Scottish and Continental authorities. It will not appear in standard common law writs or pleadings.
The more important trap for Law Mind corpus researchers is the appended maxim that follows falsa moneta in all three dictionary sources: Falsa orthographia non vitiat chartam (concessionem) — "False spelling does not vitiate a deed." Black's (both editions) and Burrill treat this as a related entry running directly from the falsa moneta headword. A researcher scanning these dictionary pages must recognize that the maxim is a separate legal proposition entirely, not a gloss or qualification on the counterfeit money definition. The physical proximity on the page has led to conflation in secondary literature. The maxim itself is a rule of deed construction, supported by Sheppard's Touchstone (pp. 55, 87), 9 Coke 48a, and Wing's Maxims (p. 19).
Researchers working in numismatic law history, monetary regulation, or the history of counterfeiting offenses should trace the doctrine through the Codex directly (Cod. 9, 24, titled De Falsa Moneta) rather than through common law sources, which address counterfeiting under distinct statutory and common law headings. In English law, coinage offenses developed along a separate track through royal prerogative and later parliamentary statute; the Latin phrase may appear as a learned citation in treatises but does not anchor a common law doctrine.
Historical Dictionary Support
All three source dictionaries are in full agreement: falsa moneta means false or counterfeit money under the civil law, and all three cite Cod. 9, 24 as the primary authority. There is no meaningful divergence among them on substance.
What the historical dictionaries do not provide is any doctrinal elaboration — no discussion of what offenses were attached to falsa moneta under Roman law, what penalties applied, or how civilian jurisdictions absorbed or adapted the doctrine. The entries function as translation aids rather than analytical tools. Researchers needing substantive content on the Roman law of coinage offenses must go directly to the Codex or to civilian commentators; the dictionary record on this term is thin by design.
The attachment of the orthographia maxim to the falsa moneta entry in Black's — present in both the first and second editions — is a dictionary formatting artifact that later researchers should handle with care. Burrill omits the maxim, which suggests it recognized them as distinct entries.
Jurisdictional Note
Falsa moneta is a civil law term with no operative force as a standalone doctrine in common law jurisdictions. Counterfeiting in English and American law is governed by statute and common law offenses that use entirely different vocabulary. The term is relevant primarily to researchers working in Roman law, civilian-influenced systems, or comparative legal history.
