Your currency-note has a life-span!

That $1 bill in your wallet probably won't be around forever. 💵⏳ A U.S. $1 note has an average circulation life of only about 6 years. Think about how much abuse a banknote can experience during that time: It gets folded, crumpled, stuffed into wallets, passed between thousands of people, exposed to dirt and moisture, and handled countless times. Eventually, a note becomes too worn or dirty to remain in circulation. When that happens, the Federal Reserve removes it from circulation and it is destroyed—while a new note takes its place. The U.S. Bureau of Engraving and Printing confirms that worn notes are removed from circulation and replaced. But there's an important detail: Six years isn't an expiration date. Some $1 bills may disappear from circulation much sooner, while others can survive considerably longer depending on how heavily they're used. So the next time you hold a dollar bill, remember: It isn't just money. It's a tiny piece of paper that may have already traveled through thousands of hands—and its journey will eventually end when it's too worn to keep circulating.
