Can money rot in a safe?

Inquiring minds want to know: could currency actually deteriorate, even if securely stored in a safe? The conventional wisdom suggests that cash is a stable asset, impervious to the elements. But what if we delve deeper? Could the humidity, temperature fluctuations, or even the chemical composition of the safe itself have a corrosive effect on the paper bills or metal coins? Could the inks fade, the paper fibers degrade, or the metal alloys corrode over time? Would this deterioration be gradual, or could it happen suddenly, leaving the owner with a stack of worthless paper or a pocketful of rusty coins? The question begs for an answer, and we seek to uncover the truth behind the proverbial safety of money in a safe.
