Expensive metals are protected by electroplating.True or false?

it is 100% false less expensive metals are electroplated by more expensive metals to give them lustre, or protect them from corrosion and scratches. Jewellery makers electroplate silver and gold on less expensive metals. And by the way gold is one of the least reactive metals so why could one try to protect it.
