Crown money box was made to celebrate the 1937 coronation of King George

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.
