As good an investment as gold without taking physical possession of said gold. The Gub’ment can declare your certifcates and the stamps worthless when they so choose. I hear it is VERY hard to actually get anything more than a promise of gold these days.
I actually have been encouraging friends not to buy just raw gold, instead, invest in something like a Gold Rolex. You have value two ways, one of course is the raw value of the gold, the other is the inherent value of the watch. This way, if Gold doesn’t hold its value, you have another value opportunity. Rolex (and a few other high-end Swiss brands) are known to hold their value well, if not go up.
