It depends on the scenario.

1) A scenario where the world will be restored to some sort of country based system, including governing bureaucracies within 5 years.

2) A secnario where the worst has happened and everyone is out for themselves.

In the first scenario gold may be valuable, but only after you have lasted the 5 year storm. In this time you will need basic supplies or the ability to live off the land.

In the second scenario gold will have little value because it has no use. People will happily trade food, fresh water, tools, seeds, sanitary products and all sorts of other things for a mountain of gold. Consider your offering to someone who needs food. You offer them gold and someone else offers them a full leg of ham. Who exactly do you think they will choose?

Gold only has value because we place value upon it. In the modern age it has a very clear use in electronic components, in past ages it had value as jewelery but only in cultures with a stable economy.
