This is certainly true.
Anyway, nothing personal, a certain approach to precious metals just gets my goat. It's not impossible to profit from them as it's not impossible to profit from anything in this world, in principle. Hell, urine was profitable enough two thousand years ago that they had a special tax on it. But you need skills and you need capital to do it, whereas this angle being sold to normal everyday people that "buy $100 worth of silver and you will profit" is just wrong. It's akin to "start your own tomato farm on your windowsill" or in the words of Carlin "how to make money by renting out the space inside your nostrils".
You wanna make money trading silver, you'd better know what you're doing.
(And for the record the catastrophic angle doesn't work either. Sure, if apocalypse hits and there's no more functioning state it would seem silver rounds might make excellent trade items.
However, the presumption that you'll get to keep/be able to use your rounds is weird in that context. If the government couldn't keep itself together you're going to manage to keep yourself glued to your coins? By what process, using what method? If such a method exists why didn't the state use it to preserve itself? You think angry dudes with guns care you bought that silver fair and square 5 years pre-Apocalypse? The peeps SOL'd during Katrina didn't do much silver coin trading. The UAF 571 didn't establish a silver price per pound of human flesh. If most of humanity is wiped we'll spend our time digging through warehouses for salvageable items, not pushing back and forth engraved metal. On it goes.)
