I don't suggest gold, I think it's overpriced at this point, just hit $1,000 FRNs/ troy oz. When everybody and his uncle jumps on it and you see ads in MSM (mainstream media) you know it's overpriced. Well - maybe not yet. OTOH, it doesn't matter that it's $1,000 /oz if it's going to $1300 next year.
The problem is that a coin of any size has too much purchasing power. It's impossible to purchase most things used in daily life even with smaller 1/4 and 1/10 oz. Silver has always been the choice of currency.
Anyway, gold has never been a monetary standard nor has it ever been the primary circulating medium. In US law, the dollar always was, and still is 371.25 grains of silver. The FR Notes were redeemable in dollars but redemption stopped. Legally, the currency in use, the Federal Reserve Note has no connection to the dollar, it's bad to call it a dollar. The layman is confused and doesn't understand the concept of redemption vs. sellling it for a fluctuating price.
Get some silver rounds, just make sure that they have the weight and the fineness stated on them. You can never go wrong with the US Silver Eagles, but my favorite is the Canadian Maple -- 999 fineness and the nominal value is $5 CAD vs $1 FRN.
I suggest getting 2/3 silver and 1/3 gold, the latter in smaller denomations, maybe 1/4 and 1/2 oz.
At this point, you have to "sell" your money, bullion that is, to get some greenbacks so you can go shopping. That may not last forever.
When the paper currency becomes so unpredictable that you don't know what it will do in 2 weeks, even Joe Six Pack will demand something stable. Let the silver ounce become the monetary standard. If everyone or even a substantial minority demands stable money, what will that do to the price of silver? And to the purchasing power of PMs? My guess, they will go up an order of magnitude.
http://usdebtclock.org/Now looking at the debt, it doesn't look good. Some say it's impossible to ever pay it back, even theoretically. Does anyone seriously believe otherwise? It will be defaulted on, via hyperinflation. If anyone has a more rational explanation, I would love to see it and I would love to accept it. When this happens, who knows. They may continue this game for a long time, decades maybe. If you get some PMs, you surely won't lose and you might even gain.
