MUNDANE MYSTERIES: How long does a $1 bill last?

More and more people are using everything but cash nowadays. Venmo, credit cards, phone apps, it’s becoming more rare to actually see real dollar bills being tossed around. But when they do… how long do they last in circulation? What’s the lifespan of one singular dollar bill.

According to the Federal Reserve, each $1 bill lasts about 6.6 years.  That’s actually longer than I thought! What’s even crazier is that the $100 bill has an average lifespan of 22.9 years. Wow.
