Hallmark
A surname that most likely began as a nickname from the medieval half-mark coin or value, later fixed in a slightly altered form.
The #7,517 most common surname in the United States (2010 Census) — about 1 in every 69,757 Americans shares it.
Etymology
This surname is generally explained as a nickname based on the medieval term half-mark, the name of a money value. The first element is simply half, and the second is mark, a monetary unit used in medieval England and elsewhere. Over time, the phrase seems to have been reshaped in speech and spelling into Hallmark, a common sort of folk-etymological change in surnames.
History
The name appears to have developed in medieval England and is cited in old surname studies as a surviving form of the earlier half-mark type. Early spellings in historical sources include forms like Half-mark and related variants, showing the shift toward the modern shape. The surname is relatively uncommon today, but it has become stable in that form rather than disappearing like many coin-based nicknames.
