Found within the set are $1 coins honoring innovation and pioneering efforts which took place in the states of Connecticut, Massachusetts, Maryland and South Carolina.

Each coin is showcased in proof quality identified by its sharp relief and a mirror-like background with frosted foregrounds which gives them a cameo-like appearance.

The dollar series launched with an inaugural 2018 coin which acknowledges the first U.S. patent, as signed by President George Washington on July 31, 1790. Four will appear annually until 2032, with one design depicting American innovation for each of the 50 states, the District of Columbia, and the U.S. territories.
