1919 Sheffield Silver Trophy with Bakelite Stand

• 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.
• Sterling Silver - Sterling silver is a mixture of 92.5% pure silver and 7.5% of another metal, usually copper. Fine silver is 99.9% pure silver, and is relatively soft and the addition of the very small amount of copper gives the metal enough strength and hardness to be worked into jewellery, decorative and household objects.
• Bakelite - Bakelite was the first completely synthetic man-made substance. Bakelite was invented in 1909 by an independent New York chemist Leo H. Baekeland. It was called the "material of a thousand uses" and used to make everything from car parts to jewellery.
  
  Although nearly all plastic from this period is known as ?Bakelite', it is important to remember that this is an umbrella term that covers many different early plastics such as Lucite and cellulose acetate, and includes Bakelite.
  
  We often think of the colour of Bakelite items as dark brown, but it was manufactured in various colours including yellow, butterscotch, red, green and brown.
  
  Bakelite could also be transparent, or marbleised by mixing two colours. Plastics were cheap to produce and could be moulded or carved in a huge variety of ways.
  
  Bakelite is most commonly associated with radio cases of the 1930s, telephones and kitchen utensils, but it was also used extensively in jewellery manufacture.
  
  Early designs from the 1920s were plainer and simpler than later examples. Geometric and floral patterns typical of Art Deco styling were popular.
  
  During its heyday in the 1930s, Bakelite jewellery was stocked by the most prestigious stores, such as Saks, Harrods and Macy?s, who dedicated a shop window display to it in 1935.
  
  Coco Chanel featured Bakelite items in her accessories collection and the material was praised frequently in Vogue magazine.
  
  Manufacture of some consumer Items were suspended in 1942 in order to concentrate manufacturing on the war effort.
  
  Small items made of Bakelite are now valuable collectables. Andy Warhol was an avid collector, and when he died in 1987, his pieces sold for record prices at Sotheby's.
