8 Quick Facts About the $100 Bill

Original image

1. The $100 is the highest value bill in circulation in the United States. The US stopped producing denominations larger than $100—$500, $1000, etc.—during WWII and halted distribution in 1969. While these larger notes are legal tender and may be accepted, the Federal Reserve Banks destroy any that are received.

2. Myanmar black market moneychangers will give you a better rate on hundreds than on $50s or $20s—and they better be clean and free of creases or they might just turn you away. Apparently Burmese moneychangers are a little OCD.   "¨"¨

3. Rumors of a new $100 have been circulating for several years now with not much to show from the Bureau of Engraving and Printing. It is supposed to combine micro-printing with tiny lenses—650,000 lenses for a single $100 bill—that will move the printed images as you move the bill. To me, this sounds like the optical illusion cards that come with Cracker Jacks.

100-euro4. The U.S. dollar has served for decades as the predominant coin of the realm for international black market transactions. Approximately three-quarters of all $100 bills circulate outside the United States. Strangely enough, the supremacy of the dollar in this shadow economy has given the U.S. economy a boost. Since most of these bills will never return stateside, this outflow of U.S. currency now serves, in essence, as a gigantic interest-free loan. A few economists have predicted that the relatively new 100 and 500 Euro notes will soon supplant the $100 bill as the worldwide shady currency of choice due to the Euro's higher value and now near-worldwide acceptance."¨"¨

5. Traces of cocaine are found on nearly four out of five bills circulated in the U.S., yet the $100, $5 and $1 have much lower traces than the $10 and $20. The truth is that probably only a fraction of these bills have actually been used to snort cocaine. Most contact with the fine powder probably comes from incidental contact in wallets, cash drawers, and money sorting machines. Random stat: Nearly 100% of Irish notes are said to contain cocaine traces."¨"¨

6. The $100 bill represents 11.9 percent of all U.S. paper currency production, with the average bill expected to last 89 months in circulation."¨"¨

100-dollar-back7. The clock on the back of a $100 bill shows the time as 4:10. According to the Bureau of Engraving and Printing, "There are no records explaining why that particular time was chosen."

8. There have been calls to demonetize the $100. (I had no idea that demonetize was a word.) Given its predominance in underworld transactions, and the lack of ordinary businesses that still accept $100 bills, some economists and pundits have called for the elimination of the hundred. We're not just talking about removal from circulation, mind you, but a total demonetization (spellcheck thinks it's a real word, too). Basically, give people a year or two to turn in all their hundreds, and after a certain point, they would no longer be valid U.S. currency. This would cripple money laundering enterprises, shut down major black market enterprises, and hurt our enemies, the proponents say. I say that if we can't get rid of the penny, what hope do we have of writing off old Ben?

6 Radiant Facts About Irène Joliot-Curie

Though her accomplishments are often overshadowed by those of her parents, the elder daughter of Marie and Pierre Curie was a brilliant researcher in her own right.

Irène’s birth in Paris in 1897 launched what would become a world-changing scientific dynasty. A restless Marie rejoined her loving husband in the laboratory shortly after the baby’s arrival. Over the next 10 years, the Curies discovered radium and polonium, founded the science of radioactivity, welcomed a second daughter, Eve, and won a Nobel Prize in Physics. The Curies expected their daughters to excel in their education and their work. And excel they did; by 1925, Irène had a doctorate in chemistry and was working in her mother’s laboratory.


Like her mother, Irène fell in love in the lab—both with her work and with another scientist. Frédéric Joliot joined the Curie team as an assistant. He and Irène quickly bonded over shared interests in sports, the arts, and human rights. The two began collaborating on research and soon married, equitably combining their names and signing their work Irène and Frédéric Joliot-Curie.

Their passion for exploration drove them ever onward into exciting new territory. A decade of experimentation yielded advances in several disciplines. They learned how the thyroid gland absorbs radioiodine and how the body metabolizes radioactive phosphates. They found ways to coax radioactive isotopes from ordinarily non-radioactive materials—a discovery that would eventually enable both nuclear power and atomic weaponry, and one that earned them the Nobel Prize in Chemistry in 1935.


The humanist principles that initially drew Irène and Frédéric together only deepened as they grew older. Both were proud members of the Socialist Party and the Comité de Vigilance des Intellectuels Antifascistes (Vigilance Committee of Anti-Fascist Intellectuals). They took great pains to keep atomic research out of Nazi hands, sealing and hiding their research as Germany occupied their country, Irène also served as undersecretary of state for scientific research of the Popular Front government.


Irène eventually scaled back her time in the lab to raise her children Hélène and Pierre. But she never slowed down, nor did she stop fighting for equality and freedom for all. Especially active in women’s rights groups, she became a member of the Comité National de l'Union des Femmes Françaises and the World Peace Council.


Irène’s extraordinary life was a mirror of her mother’s. Tragically, her death was, too. Years of watching radiation poisoning and cancer taking their toll on Marie never dissuaded Irène from her work. In 1956, dying of leukemia, she entered the Curie Hospital, where she followed her mother’s luminous footsteps into the great beyond.

You Can Now Order Food Through Facebook

After a bit of controversy over its way of aggregating news feeds and some questionable content censoring policies, it’s nice to have Facebook roll out a feature everyone can agree on: allowing you to order food without leaving the social media site.

According to a press release, Facebook says that the company decided to begin offering food delivery options after realizing that many of its users come to the social media hub to rate and discuss local eateries. Rather than hop from Facebook to the restaurant or a delivery service, you’ll be able to stay within the app and select from a menu of food choices. Just click “Order Food” from the Explore menu on a desktop interface or under the “More” option on Android or iOS devices. There, you’ll be presented with options that will accept takeout or delivery orders, as well as businesses participating with services like or EatStreet.

If you need to sign up and create an account with or Jimmy John’s, for example, you can do that without leaving Facebook. The feature is expected to be available nationally, effective immediately.
