Well that would depend what you mean, many items within the household have gold components such as your mobile phone and other electronic devices that you may have scattered around. Mostly gold is found within the wires but other components may be made up of gold as well. If you are asking about items entirely made up of gold, your best bet would be jewelery and possibly expensive ornaments (but its not probable that you'll have a solid gold ornament stashed somewhere in your house :P). Either way, many of the gold items in your house will be either easily identifiable or stuck inside some electrical item.
