One-dollar bills going into circulation next month will bear a new signature. Treasury Secretary Steven Mnuchin’s name will appear alongside the signature of Treasurer Jovita Carranza.

Joined by Carranza and Mnuchin’s wife, Louise Linton, the treasury secretary visited the Bureau of Engraving and Printing on Wednesday to witness the production of the first bills that bear the new signatures.

The signatures of the Treasury secretary and treasurer appear on every United States bill. According to the Lincoln Journal Star, Mnuchin’s signature is “decidedly more legible than that of his predecessor Jacob Lew.” Lew’s handwriting was so sloppy that the former president joked it might debase the currency.

Mnuchin did not address the changes proposed to the $20 bill, according to The Associated Press. The bill currently features former President Andrew Jackson, but a bipartisan bill seeks to replace him with an image of Harriet Tubman, the abolitionist icon who helped thousands of slaves escape to freedom, by 2020.

In late August, Mnuchin said the Treasury Department may scrap plans to replace Jackson, a plan finalized under former President Barack Obama in 2016. The next month, Mnuchin said his department is reconsidering the change.

Mnuchin and Linton took several pictures (see below) in which they displayed the new $1 bills printed on huge sheets, which were met with mean-spirited criticism on social media.
