Owner Comments:
Released in the same order as the State Quarters series, Delaware was the first state featured in the US Mint’s American Innovation Series that will run until 2032. These coins are issued for numismatic sales only and not distributed for circulation. In fact, no dollar coins have been issued for circulation since 2011.
On May 9, 1922, the International Astronomical Union passed a resolution to formally adopt Annie Jump Cannon's stellar classification system, the Harvard Classification Scheme, which was the first serious attempt to organize and classify stars based on their temperatures and spectral types. With minor changes, it is still being used for classifying stars today. In 1925, she became the first woman to receive an honorary doctorate of science from Oxford University. The reverse honors her achievements with a silhouette of Annie Jump Cannon against a field of stars. It was designed by Donna Weaver and sculpted by Chief Engraver Joseph Menna.
