Definition
A doit was a small coin of minimal value, historically used in English legal contexts to denote a negligible sum of money. In legal usage, the term appears primarily in statutes and pleadings as a unit of account representing the least possible monetary amount — functionally, a synonym for an infinitesimal or de minimis sum. The word entered English legal vocabulary through Dutch and Scottish coinage traditions and was recognized in English law chiefly as a base coin whose circulation was restricted by statute (3 Hen. V, c. 1). Its legal significance lies less in any precise monetary denomination than in its rhetorical and doctrinal function as the floor of monetary valuation.
Common Language
Modern common usage (Wiktionary): A small Dutch coin equal to one-eighth of a stiver; also used figuratively to mean a small amount or bit.
Historical common usage (Webster's 1913): A small Dutch coin worth about half a farthing; also used in Scottish currency; figuratively, any trifling amount of money — as in "I care not a doit."
The gap between common and legal usage here is narrow but worth noting. In ordinary language, the doit functions almost entirely as a figure of speech denoting worthlessness. In legal sources, it carried the additional weight of statutory prohibition — base coins including the doit were formally banned from circulation under English law — making it not merely a rhetorical floor but a legally defined category of debased currency.
Common Confusion
The doit is occasionally confused with other small-denomination coins appearing in historical legal texts, such as the mite, farthing, or halfpenny. These terms are not interchangeable. A farthing was a recognized denomination of English sterling coinage with ongoing legal validity; the doit, by contrast, was a foreign or base coin specifically targeted for prohibition. In pleadings and damages assessments, the distinction matters when evaluating whether a court record is referencing a cognizable English denomination or invoking the doit rhetorically to signal nominal or contemptuous damages.
Why It Matters in Research
Researchers encountering "doit" in historical legal materials should treat it primarily as a rhetorical signal rather than a precise monetary figure. When a damages award is described as amounting to a doit, or when a party is said to owe not a doit, the term is functioning the way "cent" or "penny" functions in modern idiom — as an expression of triviality — rather than specifying an actual sum to be calculated.
The statutory prohibition in 3 Hen. V, c. 1 is the term's most substantive legal anchoring. Researchers working in early fifteenth-century English commercial or currency law will find the doit relevant to questions about what coins could legally circulate and what remedies existed against base-coin fraud. Outside that narrow statutory context, appearances of the term in case law, pleadings, or writs are almost always idiomatic.
Watch for variant spellings. Black's Supplemental entry renders "ATKIN, or DOIT" — almost certainly a printing or transcription artifact for "DOTKIN, or DOIT" — suggesting early dictionary sources handled the term inconsistently. Corpus searches should include variant forms: doit, doyt, dotkin, and doitkin.
The term has essentially no live legal significance in modern practice. Its value to the Law Mind researcher is historical and interpretive: understanding that a medieval or early modern pleader who invoked the doit was reaching for the legal equivalent of "not worth a penny."
Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) Supplemental is the sole legal dictionary source available here, and its entry is brief. It correctly identifies the statutory prohibition (3 Hen. V, c. 1), attributes the definition to Jacob's Law Dictionary, and notes the survival of the term in figurative speech. The Jacob attribution is significant: Giles Jacob's Law Dictionary (various editions, early 18th century) was a primary conduit through which archaic monetary terms entered the later common-law dictionary tradition, and Black's appears to have drawn this entry directly from that lineage without independent elaboration.
Webster's 1913 and Wiktionary together provide richer monetary context than the legal dictionary does, which is itself informative — by the time of Black's second edition, the doit had so thoroughly left active legal usage that the compiler saw no need to expand beyond Jacob's original note.
No major legal dictionary provides a detailed treatment of the doit's role in the law of debasement or currency regulation, leaving a gap that researchers pursuing those questions must fill through primary statutory sources.
Jurisdictional Note
The doit's legal prohibition was an English statutory matter. Scottish law recognized the doit as a domestic coin, not merely a foreign base coin, giving it a somewhat different status in Scottish legal and commercial records. Researchers working in Scottish historical sources should not assume that English statutory prohibitions on the doit applied equally north of the border.
