I'm also heavily invested in brass, which will be more valuable should any kind of domestic situation occur that requires physical gold or silver be used in place of cash.

When Y2K was rolling around, some of my tinfoil hat coworkers would talk openly about all the supplies they had stocked up. They asked me what I had stockpiled. "Only brass, mostly 5,56. But, thanks for letting me know where I can come and get perishable goods if needed."

I'm all for diversification, and do truthfully have some investments in precious metals, but not for some end-of-days kind of scenario.
