The 2019 Reverse Proof Delaware American Innovation Dollar PF70 honors astronomer Annie Jump Cannon and her groundbreaking work in stellar classification. This reverse proof coin from the American Innovation series commemorates Cannon's development of the Harvard Classification System, which organized stars by temperature and spectral characteristics - a system that remains fundamental to astronomy today. Certified in perfect PF70 condition by NGC with the special "First Day of Release" label, this coin represents the highest possible grade for proof coinage, with flawless surfaces and sharp striking details.
The reverse proof finish gives this coin its distinctive appearance, with frosted fields and mirror-like devices that invert the traditional proof presentation. The design features symbolic representations of Cannon's astronomical work, including stellar imagery and references to her classification system. As part of the American Innovation dollar series, this coin celebrates Delaware's contribution to scientific progress through Cannon's pioneering research at Harvard University. The First Day of Release designation indicates this specimen was among the initial coins distributed when the series launched, adding historical significance to its numismatic value. This certified perfect example preserves both the artistic merit of the coin's design and the legacy of a remarkable female scientist whose work fundamentally changed our understanding of the universe.
