Why do US submarines carry a coin?
Could you elaborate on the significance of US submarines carrying a coin? Is it a tradition rooted in history, or does it serve a practical purpose? What kind of coin do they typically carry, and what symbolism does it hold? Furthermore, are there any regulations or policies governing this practice, and how does it impact the submarine's operations or the crew's morale? I'm intrigued by this custom and would love to gain a deeper understanding of its origins and significance.
