I think you will find these interesting. The above is on coin collecting during PM hoarding times.
I am also listening to this presentation found by following "theendofamerica15.com" that I heard about on the radio a zillion times. Almost turned it off at the beginning. Glad I kept with it. Interesting analysis of the current economic situation.

Although I found this informative, I am not endorsing buying any of his publications. Mostly info available free with a little research.
Enjoy.
