    This Coronation Crown money box was made to celebrate the 1937 coronation of King George VI .  Both components are made of brass plated zinc, shown by the white metal showing through where the plating has worn.
     
    This miniature candlestick is also brass-plated zinc alloy diecasting.  For a cheap souvenir it has far more close detail than could easily be obtained in brass but feels lighter in weight.
     
    The underside shows a detailed 'Gunga Din' manufacturer's mark in raised lettering with a high definition that is easiest to achieve by diecasting in zinc. Moorgate (Birmingham)
     
  Heart shaped souvenir of the copper mine at Bingham Canyon in Utah. This is the world's largest man-made excavation, being more than 4km ( 2 1/2 miles) across at the top, 1km (3/4 mile) deep and covering 800 hectares (1,900 acres). Bingham Canyon ore has yielded more than 15 million tons of copper but this souvenir is made of copper plated zinc.

   Any of these might make a monkey out of the brass buyer.  The one on the right is copper plated plastic, the others are plated zinc diecastings.  They are lighter in weight than comparable brass castings and a scratch test on the underside shows white metal.

    An early Rawlplug gauge for checking size of woodscrews needed for each wallplug size.  It is made of copper-plated steel and jumps to a magnet.
   
     
  Plaque marked 'Sumo Cobre Mexico SA&CV 9689', very light and probably made of copper loaded resin.
