The largest denomination in everyday use was a $10,000 note, excluding the $100,000 gold certificate the Fed issued to move money between banks.

Only a few hundred of those identical banknotes are thought to be in circulation today, making them highly desirable to collectors.

2. More Than Two-Thirds of $100 Bills Are Held Outside the US

Over two-thirds of $100 bills circulate outside the United States, residing in foreign banks and safe deposits. Despite the vast sums of money Americans transact within their borders annually, the preference for holding the $100 note abroad underscores its status as a favored reserve currency globally. Thanks to the dollar’s reputation for stability, it is widely used for debt payments and funding state-supported projects. Consequently, those accumulating dollars abroad are less concerned about the potential devaluation they might face with other currencies.

3. The Dollar is the Most Traded Currency in the World By Far

On the multi-trillion-dollar foreign exchange market, traders swap US dollars for other currencies in every corner of the globe, often hoping to exploit the value difference between the leading reserve currency and other currencies.

4. Dollar Bills Can Be Folded Up To 8000 Times

US dollar bills can withstand up to 8,000 folds, far exceeding the folding endurance of ordinary paper, which typically succumbs after about twelve folds. Contrary to the common belief that paper can only be folded eight times, the resilience of dollar bills comes from their distinctive composition of cotton and linen rather than the traditional paper materials. This choice of materials ensures that dollar bills maintain their integrity through various conditions, contributing to their longevity and durability.

5. The Green Color Was Used to Prevent Counterfeiting 

The distinctive green color of the US dollar, now a globally recognized feature, was initially chosen as a countermeasure against counterfeiting. In the 19th century, most of the world’s paper currencies, including the dollar, were printed in black and white. This monochromatic scheme made it easier for counterfeiters to replicate bills using the black-and-white photography available at the time. 

To combat this vulnerability, the Federal Reserve sought a solution that would hinder the efforts of forgers. They found it in the green dye, a pigment not readily accessible to the general public during that era. The rarity of the green dye made it a strategic choice, as it significantly raised the barrier to produce convincing counterfeit bills. This decision helped safeguard the currency’s integrity and cemented the greenback’s iconic appearance, setting it apart from other currencies and making it harder for counterfeiters to imitate successfully.

6. 27 Countries Accept the US Dollar as Currency 

In another stark reminder of the US dollar’s global pre-eminence, 27 countries now accept it as legal tender within their territory. The world’s second-largest reserve currency, the euro, only has 19 countries that accept it as legal tender. The British Virgin Islands, Ecuador, Barbados, and Vietnam are just a few countries that officially accept US dollars for goods and services. Some of this is that businesses can often enjoy better exchange rates when they receive the more sought-after dollars, while some of it is simply because dollars are everywhere. Global travelers are most likely to have them in abundance.
