Money is power. But who's on our money - or isn’t - can be just as powerful. While Lady Liberty has graced American coins and dollars for most of our history, it wasn’t until the 1970s that a real woman appeared on a circulating American coin. But that's about to change. Congress recently authorized the creation of twenty new quarters featuring American women from history. But how do we decide whose likeness gets engraved in our national story? And who makes these decisions? We’ll follow the money to find out. Guests: Jennifer Schneider, former program manager at Smithsonian American Women’s History Museum, current assistant registrar of outgoing and government loans at the Smithsonian American Art Museum Tey Marianna Nunn, former director of the American Women’s History Initiative at the Smithsonian American Women’s History Museum, current associate director for content and interpretation at the Smithsonian’s National Museum of the American Latino Ellen Feingold, curator of the National Numismatic Collection at the Smithsonian’s National Museum of American History Joseph Menna, chief engraver at the United States Mint Tim Grant, public affairs manager at the United States Mint Dave Clark, supervisor of blanking annealing and upsetting at the United States Mint

Did you know a person born on February 29 is called a "leapling"? This special episode is hopping with Leap Day trivia! Like, why do we need an extra day every four years anyway? And will I get paid for working an extra day in February? It's the lowdown on Leap Day in an episode that's as off-kilter as the earth's axis. Guest: Bob Craddock, Geologist at the Smithsonian's National Air and Space Museum's Center for Earth and Planetary Studies

As long as there have been wars, animals have joined their human companions on the battlefield. But a few have served so bravely they’ve been memorialized at the Smithsonian.

Virginia Hall dreamed of being America’s first female ambassador. Instead, she became a spy. Joining the ranks of the U.S.’s first civilian spy network, she operated alone in occupied France, where she built French Resistance networks, delivered critical intelligence, and sold cheese to the enemy. All on one leg. Guests: Sonia Purnell, author of “A Woman of No Importance: the Untold Story of the American Spy who Helped Win World War II.”  Randy Burkett, CIA Staff Historian Christina Gebhard, museum specialist at the Smithsonian’s National Museum of Natural History

It’s a song we often hear at the start of the new year. But what does “auld lang syne” even mean? And how did it come to be associated with New Year's Eve? With a little musical sleuthing, we find Charlie Chaplin might have something to do with it… Guests: James Deutsch, curator of folklife and popular culture at the Smithsonian Center for Folklife and Cultural Heritage

North American River Otters are popping up in places they haven't been seen in decades and nobody really knows why.

When Maggie Kuhn was forced to retire from the job she loved at age 65, her colleagues gave her a sewing machine as a parting gift. Outraged, she shut the sewing machine in a closet and, instead, stitched together the first-ever movement against ageism in the U.S. The Gray Panthers would galvanize gray haired citizenry and youth alike to challenge the way Americans think about aging.  Guests: Katherine Ott, curator and historian in the Division of Medicine and Science at the Smithsonian's National Museum of American History Emily Krichbaum, founding director for the Center for Girls' and Young Women's Leadership at Columbus School for Girls and scholar of women’s history Paul Nathanson, founder and former executive director of Justice in Aging (formerly the National Senior Citizens Law Center), a national advocacy group for the elderly poor Jack Kupferman, president of Gray Panthers NYC

All three Giant Pandas are leaving the Smithsonian's National Zoo for China by the end of the year. What's up with that?! We sat down with the director of the Zoo, Brandie Smith, to find out why the pandas are leaving, and whether China plans to send more. This might truly be the end of a beara ... we mean era! Guests: Brandie Smith, John and Adrienne Mars Director of the Smithsonian’s National Zoo and Conservation Biology Institute Stephen Powers, panda fan

The Smithsonian Institution was founded on principles of reason and scientific inquiry. So why is the Smithsonian home to countless tales of unexplained phenomena and—dare we say—ghost sightings? Inspired by an apparition at the National Museum of American History, we creak across museum attic floorboards, sneak into an old house in the woods, and even travel back in time to bring you a collection of spooky stories that can only be found at the Smithsonian.

Looks like these criminals used correct postage, 'cause justice is about to be delivered. Okay, there are no snappy one-liners in this crime scene investigation, but there are explosions, collisions, manhunts and even a cow who was in the wrong place at the wrong time. On the centennial of "The Last Great Train Robbery," we re-examine the evidence to find out how U.S. Postal Inspectors tracked down a band of old school outlaws using cutting edge criminal forensics...and postmarked them for prison. Guests: Lynn Heidelbaugh, curator at the Smithsonian National Postal Museum Chelsea Rose, Director of the Southern Oregon University Laboratory of Anthropology Kate Winkler Dawson, author of American Sherlock: Murder, Forensics and the Birth of American CSI

Cellphones put the power of the world at our fingertips. With the touch of a finger, you can instantly connect with your doctor, have food delivered to your office or simply obliterate your niece at Words with Friends. And it's all made possible by rocks formed millions of years ago, deep underground. Join us as we bust open our devices to figure out how these stones power our phones. Guests: Joshua A. Bell, curator of globalization at the Smithsonian’s National Museum of Natural History Michael Wise, geologist in the department of mineral sciences at the Smithsonian's National Museum of Natural History Josh Lepawsky, professor of geography at Memorial University of Newfoundland

Icky Gunk. Moldy Hay. Kermit. You might recognize one of these names. Before Kermit joined Miss Piggy and Big Bird, he was kicking it with Sam and Friends — a local tv show in Washington, D.C. that launched Jim Henson's career. We journey back to 1955 to figure out how this eccentric cast of puppets built the foundation for everything Jim Henson would do afterwards, from Sesame Street, to The Muppet Show and even Labyrinth (we see you, David Bowie fans). And we venture into the conservation labs to learn what it took to revive these crumbling hunks of foam and fabric when they landed at the Smithsonian. Guests: Ryan Lintelman, curator at the Smithsonian National Museum of American History  Sunae Park Evans, senior costume conservator at the Smithsonian National Museum of American History  Bonnie Erickson, a director of The Jim Henson Legacy; creator of Miss Piggy  Craig Shemin, author of Sam and Friends: The Story of Jim Henson's First Television Show
