As all of the profitable quarter series were coming to an end in 2021, the minted shifted it's multi-design program to the new "Innovation" series. Unlike the Statehood quarter series, it consists of four different designs per year (instead of five) from 2019-2032. They are to be released in order of statehood, followed by Washington, DC, and the five territories. In addition, the initial 2018 coin featured a tribute to the "Signed First Patent" by George Washington making 57 different designs in total.
Each coin in the series includes business strikes with P and D mintmarks, and both proof and reverse proof strikes with an S mintmark. Mintmarks, like the motto E PLURIBUS UNUM, are incused into the coin's edge.
