If you do buy gold make sure you are actually buying the metal and keep it yourself , don't get into the whole paper gold market.
On a related note jewerly can be of more use than bullion in certain circumstances.

the bit about the gold
Someone hit me in the head please because I messed up about the gold issue.
Everyone wants to buy gold! “I buy gold. Pay cash” signs are everywhere, even on TV! I can’t believe I’m that silly! I just didn’t relate it to what I read here because they deal with junk gold, like jewelry, either stolen or sold because they needed the money, not the gold coins that you guys talk about. No one pays for the true value of the stuff, so big WARNING! Sign on people that are buying gold coins. Since it is impossible to determine the true mineral percentage of gold, small shops and dealers will pay for it as regular jewelry gold. What I would do if I were you: Besides gold coins, buy a lot of small gold rings and other jewelry. They should be less expensive than gold coins, and if the SHTF bad, you’ll not be loosing money, selling premium quality gold coins for the price of junk gold. If I could travel back in time, I’d buy a small bag worth of gold rings.
Small time thieves will snatch gold chains right out of your neck and sell them at these small dealers found everywhere. This is VERY common at train stations, subways and other crowded areas.
So, my advice, if you are preparing for a small economical crisis, gold coins make sense. You will keep the value of the stuff and be able to sell it for its actual cost to gold dealers or maybe other survivalists that know the true value of the item. In my case, gold coins would have been an excellent investment, saving me from loosing money when the local economy crashed. Even though things are bad, I can go to a bank down town and get paid for what a gold coin is truly worth, same goes for pure silver. But where I live, in my local are small time dealers will only pay you the value of junk gold, no matter what kind of gold you have. So, I’d have to say that if TSHTF bad, gold jewelry is a better trade item than gold coins. Forgive me for not talking about this before, but I didn’t realize this until today, when I visited my local market warehouse and saw a “Buy Gold” sign.
