Sometimes, you just don't want people to see your personal photos. And if you're really, really paranoid about them being found, well, you need to take some drastic measures. Like by hiding them on a MicroSD card inside a hollow nickel.
The hollow nickel in question is available for $30, which is a small price to pay for the peace of mind that comes with knowing that your memory card is stored safely in… one of these nickels. Crap, which one is it? Why did I mix it up with all of my other change? Oh no. Did I spend it at that gas station? I'm such an idiot! What was I thinking??
