People of Argentina had little use for gold, why, because there was nowhere to convert gold into usable barter. The piece I read , written by a man whom lived the economic collapse. He stocked up on coin, large quantities of a variety of coin, which like the United States is minted by Congress, not the federal reserve. Coin for this man was used for taxis, food, etc. A flexible money useful in daily life.
He also bartered pieces of gold jewelry for higher expenses.

So, store some silver and gold, but coin is also recommended.
