the gold bulls are desperate.
your question prompted me to call my local coin dealer down the street. the markup for a Kruggerand over spot is 4%. it's been that for years back when i was buying in 2005.
I always found the Sprott physical silver and gold trust premium/discount percentage to be a good indicator for whether these conspiracy theories have any merit. A higher premium trend would make me possibly believe in them. However, since last year, the premium has virtually disappeared between physical and paper. Remember, the market will almost always warn of an imminent problem if there was one.
