Precious metals are speculative investments. There are many ways to profit. One is to buy when it's low--as back at $300 for gold and $4 for silver--and add some on the way up. When you think it's peaked, sell off about a third or a half. Invest the profit as you see fit.
Trouble is, most people haven't paid attention over the last ten or fifteen years, and by the time they figure out it MIGHT be a good thing, they're late to the party. That happened to a lot of people when the Hunt brothers manipulated the silver market in 1979-1980, and folks got badly burned. Many of them STILL don't understand what happened.
The least-cost way to buy silver is what are called "Junk US silver coins". Dimes, quarters and halves minted in 1964 and earlier. That's the minimum premium over bullion value. The bullion value is 0.712 times the spot price of silver, per dollar, per thosuand dollars, whatever. A $1,000 bag will cost 0.712 times the spot price of silver, plus a small premium. The buy-back would be near the spot value.
Odds are, right now, that the dollar will continue its decline. Inflation will continue at it's real rate--which I, me, Ol' Art, thinks is around double the offficial number. The Chinese government has said it's gonna keep buying gold in ton-sized lots. They're talking about starting a gold ETF (look that up) which would do to gold what the silver ETF has done to silver: Push up the price.
Right now, I'd pick gold/silver over guns. Been working that way for over a year, now. No signs yet of stopping.
