Australian Colonial Silver Butter Knife by Alexander Dick, circa 1837

• Hallmarks - A mark stamped on articles of precious metals in Britain, since the 14th century, certifying their purity. It derives its name from the Guild Hall of the Goldsmiths' Company, who recieved its Charter in 1327 giving it the power to assay (test the purity) and mark articles of gold and silver.
  
  The hallmark will consist of several marks, including the:
  
  - silver standard mark, indicating the purity of the metal. Sterling silver is .925 pure silver.
  
  - the city mark indicating the city in which it was assayed eg London, Birmingham, York etc.
  
  - the date mark, usually a letter of the alphabet in a particular font and case,
  
  - a duty mark, indicating whether duty had been paid to the crown, and only in use from 1784 to 1890
  
  The piece may include an additional mark, the maker's mark, although not forming part of the hallmark, will be located in the vicinity of the hallmarks.
  
  Sometimes silver plated items will bear faux hallmarks, often confusing those not familiar with silver markings.
• Date Letter on Silver - A date letter is a letter or symbol that is used to mark silver and other precious metals to indicate the year in which the piece was made. The date letter system is used by the British hallmarking system and it is a way to verify that a piece of silver is genuine and has been assayed (tested) by an official assay office.
  
  The date letter system has been in use since the 14th century and it changes every year, so it is possible to identify the year in which a piece of silver was made by looking at the date letter. The date letter is usually stamped alongside other hallmarks such as the maker's mark, and the standard mark (indicating the fineness of the metal) on the silver piece. The style of the letters varies depending on the assay office, and the style of the lettering also changes over time. The date letter is usually placed inside a shield shape, sometimes accompanied by other symbols.
  
  The date letter system is not used in all countries, so if a piece of silver does not have a date letter, it does not necessarily mean it is not authentic. The date letter system is not always used for small or insignificant silver items.
• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
