This topic is near and dear to my investing interests. It's good that you mention 'without physical possession', because with the exception of coins, having a place to 'store' bullion can be unsafe as well as subject to seizure. (But that's a whole different thread.)

I've checked into many of these sites. In addition, I have some connections with dealers who only work with large quantities to trade, take possession, or resell.
Some think gold is in a bubble. If this is the case, it has been floating steadily along, and continues to see growth.
