Unless you are super-rich and want bullion in multiple banks in multiple EU countries where you own multiple homes, I don't understand why you would give your disaster insurance gold holdings to someone else to hold for you.
If you don't want metals in your house the gold or sliver stock funds would be the way to go over letting someone else hold your metal for you if one wanted to go down the PM investing route. At least the stocks can be sold in seconds from your computer
Also, sdb's work if you don't want it around the house. I haven't looked into the comex yet. Paper isn't my thing and I don't wanna lose my arse on a learning curve
They're basically like any other stock you can do on Etrade ect. For a pure metals play I would personally prefer the paper stock version as you can sell it all in an instant and don't have to worry about finding a buyer which is especially difficult when price tops out and starts sliding down
GLD and IAU are the 2 largest gold-related ETFs. GLD is over $20 BB in assets, IAU and SLV are about $5 BB each. ETFs are supposed to trade right about at NAV, but double-check off a site like XTF.com. You don't want to go long a big premium or short a big discount (very rare) and then lose on premium loss or discount gain. Those rarities aside....if gold collapsed but you were waiting for funds to buy some coins you would go LONG the GLD or IAU. Any higher prices on the coins would be offset by the gains on the ETFs.
