If I'm in a scenario where the economy has collapsed to the point that trade is happening through barter, I feel like liquor, arms, and ammunition are better value stores than precious metals. They'd be an appreciating asset, because a societal collapse would probably disrupt manufacturing and distribution supply chains, and they're directly useful rather than requiring someone figure they'll be able to exchange them with someone else later, but also shelf stable enough that a buyer could trust they could pass them off later, allowing them to operate as an adequate substitution for currency.
