gold coins -- pick them up at your local dealer for $50 -$70 per ounce above the spot price of gold
For most investors with a long time horizon, I'd recommend a very diversified portfolio with most or all of the above in addition to significant chunk of US stocks (VTI -- Vanguard total index is the only thing you need to hold there) and a good chunk of cash/short-term CDs.
I still hold all of the above, or their functional equivalents, with the exception of the the foreign bond fund. With fiat currencies around the world likely to continue competitive devaluation, I'm not that enthusiastic about bonds anywhere.
Since then, I've also come to strongly prefer physical metals over the ETFs. And I'd take the Pimco Commodity Fund (PCRCX, PCRRX) over the GSG.
I also mentioned real estate in the post. Ironically, the one thing Zimbabwe Ben most wants to inflate is the one thing he hasn't been able to yet. It's still an open question whether the dollar collapse will be big enough to overcome today's still-high real estate valuations. But if it does, 4-to-1 leverage with a 30-year-fixed mortgage is a great way to play it.
