Pinchbeck, an alloy of copper (about 90%) and zinc (10%), is also known as 'poor man's gold'. This alloy is named after the watchmaker Christopher Pinchbeck who invented it in the 18th century. The invention of pinchbeck allowed ordinary people to buy 'gold effect' jewellery. Those who do not look carefully may be fooled into thinking this is gold. While resembling gold when newly made, pinchbeck darkens with age and does not bear any gold hallmarks.
