Frankly, I would have been happier seeing Harriet Tubman on the $20 bill."Currency is redesigned to stay ahead of counterfeiting," the US Treasury says. "The ACD Steering Committee recommended a redesign of the $10 note next. The ACD will make its next recommendation based on current and potential security threats to currency notes."
The ACD bases those recommendations on the "current and potential security threats to currency notes," and it turns out that the $10 bill is at a greater threat of being counterfeit than the $20 bill.
- Why the US Treasury is changing the $10 bill instead of the 20
