What this could mean for the current mug of the $10 bill — Lew's treasury predecessor Alexander Hamilton — has become the subject of much speculation.
A tweet on Wednesday from Lin-Manuel Miranda, creator and star of the Broadway hit musical Hamilton — based on the founding father's life — suggested Hamilton will still feature on the bill in some capacity.
The Treasury Department, which hosted Miranda at its headquarters before the Hamilton cast's White House performance on Monday, remained tight-lipped about the details, but it did confirm that Hamilton will still be honored on the redesigned bill.
"The Secretary thanked Miranda for the ingenious way in which he has been able to tell Hamilton's story and ignite a renewed interest in one of our nation's founding fathers," a treasury spokeswoman told the New York Times. "Secretary Lew also reiterated his commitment to continue to honor Alexander Hamilton on the 10 dollar bill."
The identity of the woman to feature on the new bill remains anonymous; however, a groundswell of support for Underground Railroad organizer Harriet Tubman puts her in the running. A poll in May, organized by Women on 20s, advocating for the inclusion of women on American currency, landed Tubman in first place.
While the mystery of the design remains, we're putting our money on something awesome.
