Following the conclusion of the National Parks quarter series in 2021, Flanagan's original design was restored to the obverse, with the reverse a representation of Washington crossing the Delaware River on the night of December 25, 1776. Treasury Secretary Steven Mnuchin had the option of ordering a second round of 56 national parks quarters, but did not do so by the end of 2018 as required in the 2008 legislation. In October, 2019, the Citizens Coinage Advisory Committee met to consider designs; with the final choice made by Mnuchin. On December 25, 2020, the Mint announced the successful design, by Benjamin Sowards as sculpted by Michael Gaudioso. The 2021 quarters with that design are to be released into circulation on April 5, 2021.
