Actually Jim, it is COMPLETELY correct.
Read my reply again, and you can see my mention of the Hunt-bubble, which is the same bubble you were talking about in 79-80.
Luckily for my Dad, he was smart enough to unload his silver halves right before the bubble popped, but A LOT of people weren't so lucky, as silver dropped extremely quickly once the Government decided it didn't like the Hunt brother manipulation on the market. Not everyone saw that drop coming so suddenly and were left with there silver where it remained at $5 an ounce or so for multiple decades after that burst.
I see what you are saying about it not ONLY being 50+ years of hoarding, but even then it was 15+ years of hoarding and you still needed to know when to sell and be aware of the market. I still don't want to hoard copper pennies today and wait for 15+ years for a profit... if you see what I am saying.
