If you see $15,000 Gold ounces, you're in a hyperinflation environment. Milk and bread will cost $100 and you might as well wipe your ass with your fiat paper bills.
Silver is where it's at. Gold is prettier, but silver is more finite, and has more industrial uses than gold. Silver is MAJORLY MAJORLY MAJORLY undervalued in the current $30 range, and imo it was majorly undervalued in the $49.99 dollar range too. If you're going to buy metals, I would make silver 80% and gold/platinum/palladium the other 20%, unless you just go straight 100% silver. That's the best choice IMO.
(Besides guns and ammo of course, which will be priceless in a shit-hits-the-fan environment.)
