What about Silver?
Gold and Silver usually rise and fall together.
We have junk silver and I would encourage everyone to have some. When our fiat currency fails silver will be the fall back coinage for everyday use like buying food etc. Gold will be for large purchases.
If gas gets too expensive, you can ride him to work.
On the more serious side, i see a lot of ads touting silver now - similar to what was going on with gold before it hit its current wall. Since silver is so low now, it probably isn't a bad hedge if purchased before it does its uptick. I'm not buying anything right now.
