United States $50 gold coins(mintage created by Ronald Reagan).
Actually, any bullion gold coins are ok but I like those minted by the US. Even older US gold coins with low numistic value are nice to have. You should have started buying gold when bush got elected, but it is not too late unless you think bush can balance our federal budget and bring back our jobs and factories back from china and india in the very near future.
What is your opinion on such ventures as www.e-gold.com ?
Ironically, I think some of the Asian countries that we are running big trade deficits are going to get burned the most from the declining Dollar. Japan and Red China have been making huge investment in US Treasury securities to keep the Dollar overvalued and thus their exports to US relatively cheap. These countries are essentially defending the Dollar for us while we don't lift a hand.
Japan is in slightly better shape; they tend to buy more equities thus higher returns to offset any exchange rate losses. Plus they have a floating exchange rate. China has much less flexibility since they have to maintain the $-Yuan peg.
Of course, if the US is in a crisis situation, you may be ordered to turn in those bullion gold coins at face value... Since the government now demands gold dealers provide customer information to big brother, you will be forced to account for your purchases.
Coins with numismatic value were exempted from the gold seizure of 1933. I guess FDR had a collection.
