FWIW, we inherited our financial advisor from DW's parents after they passed and we took over the family trust. He and his team are VERY conservative and in for the long haul. Very trustworthy and on top of things in the financial world. During our last discussions he made an interesting comment regarding precious metals. The jest of the conversation was that he, according to his research and experience expected gold, in particular, to hit $6,000/ounce in ten years time. Which, as we've already discussed here in this thread and others shows you how much the US dollar will have devalued due to inflation and other things.
He has not advised buying a bunch of precious metals....BUT, said it wouldn't hurt to have at least a month or so worth of income in precious metals: Gold and Silver as a hedge. At least three to six months of income in cash saved and on hand, not in an account or bank or safe deposit box, but somewhere that you had safe and immediate access to.
One of the issues he pointed out regarding PM's is that the general population's unfamiliarity with them. It will take time should the economy switch back to REAL MONEY for people to learn and become comfortable with their everyday use again. And you can bet there will be forgers going nutz putting out bogus coin. So in general I've stuck with American Silver and American "junk silver" that's easily recognizable to most folks. Don't have a lot, but working on it slowly but surely. FWIW - YMMV.
