The 2019 Delaware American Innovation Dollar coin "features a silhouette of Annie Jump Cannon against the night sky, with a number of stars visible in the sky.” She became an internationally renowned astronomer and invented a system for classifying the stars that we still use today. Cannon was born in 1843 in the state of Delaware. Many companies are charging $3.99 or more for these individual coins. Don't be fooled into paying more. Our coins are hand selected for eye appeal and collectibility and are the same brilliant uncirculated coins, or better.
