    • 1854, Hugh Tilsley, A Treatise on the Stamp Laws, in Great Britain and Ireland:
      In Scotland the marks on silver of 11 oz. 2 dwts. are precisely the same as those on gold of 22 carats standard; and so it was, also, in England until the 7 & 8 Vict. c. 22, by s. 15 of which the gold plate mark was altered.
    • 1883, Hall marks on gold and silver plate:
      Last autumn a gentleman who is well acquainted with plate marks saw this plate, and informed the owner that it was spurious.

      The coat of arms, trademark, and Haus- and Hofmarken when used to identify property owned by a person, family, or institution; the personal device or seal employed to "sign" or notarize contracts and other legal documents; the marks of stonemasons, which indicated the identity of theproducer so that he could be paid for the pieces he fashioned; and the goldsmith's plate mark, which identified the maker and guaranteed the quality of the gold used — all these were ways of registering the person in law and commerce within the culture out of which Du:rer emerged.
