Definition
In old English law, a clipper of money — that is, a person who shaved or clipped the edges of metallic coins to fraudulently extract precious metal, then returned the debased coins to circulation at face value. The term is Latin and derives from the practice of clipping or shearing (retondere), and appears in Fleta, a thirteenth-century English legal treatise, as a classification of criminal offender. Coin clipping was treated as a serious offense in medieval England, closely associated with currency debasement and, in its more aggravated forms, charged under the law of treason or counterfeiting.
Common Language
Modern common usage (Wiktionary): No current entry; the term has no living common usage in English.
Historical common usage (Webster's 1913): Not listed; the term had passed out of general use well before the nineteenth century.
Editorial note: This is pure legal and historical Latin jargon with no common English counterpart. The underlying practice — coin clipping — is familiar to economic historians, but the term retonsor itself belongs entirely to the medieval legal lexicon.
Why It Matters in Research
Retonsor is an archaic term unlikely to appear outside of medieval legal treatises and early English criminal law sources. Researchers encountering it in primary sources should understand it as a technical classification of offender, not a general descriptive label. Its appearance in Fleta signals a formal taxonomic treatment of currency crimes in thirteenth-century English law, where distinctions between clipping, counterfeiting, and uttering false coin carried significant legal weight — including the potential for capital punishment.
The term will not appear in modern statutory or case law. Researchers working on the history of coinage offenses, treason law, or economic regulation in medieval England should trace the line from retonsor through later statutes addressing coin clipping, including the Treason Act 1351 and subsequent currency legislation, where the conduct was absorbed into broader statutory frameworks without retaining the Latin term.
The fragment appearing in the first edition of Black's Law Dictionary under this headword is garbled by typesetting error — the preceding entry on indorsers appears to have bled into the retonsor entry. Researchers should rely on the second edition of Black's or Burrill's for a clean definition.
Historical Dictionary Support
All three source dictionaries agree on the core definition: a clipper of money, derived from retondere, as recorded in Fleta, lib. 1, c. 20, § 122. Burrill's is the most precise, supplying the Latin derivation and the specific Fleta citation cleanly. Both editions of Black's reproduce the Fleta reference but the first edition entry is textually corrupted, with an unrelated passage about bills of exchange appearing immediately before the retonsor headword — an artifact of typesetting, not a substantive divergence in legal meaning.
None of the historical dictionaries elaborate on the legal consequences that attached to a retonsor under old English law, the relationship of coin clipping to treason doctrine, or the procedural context in which the term would have been employed. Researchers should not treat these entries as comprehensive accounts of the offense; they are identifications of the term only.
Fleta itself, the ultimate source for all three dictionary entries, is a Latin legal treatise of uncertain authorship dating to approximately 1290, modeled on Bracton. It is the controlling primary source for the term's legal meaning.
Jurisdictional Note
Retonsor is specific to old English law. It has no recognized equivalent in civil law systems or in American legal history, where currency offenses developed under distinct federal constitutional and statutory frameworks from the founding period onward.
