Scientific invention is highlighted in the newest United States Mint product for collectors with today’s release of the 2020-S Reverse Proof Connecticut American Innovation Dollar.
Heinz Joseph Gerber’s innovative Gerber Variable Scale is depicted on the coin. Gerber invented the device while studying aeronautical engineering at Rensselaer Polytechnic Institute in 1945, just a few years after escaping Nazi-controlled Austria.
Opposite of regular proof coins, the dollar has a unique reverse proof finish with polished mirror-like design elements that contrast against a frosted background.
The following two photos highlight differences between proof and reverse proof coins by showing previously released 2019 Delaware American Innovation dollars in each collector quality.
Designs on Connecticut American Innovation Dollar
The dollar’s reverse (tails side) design, created by Richard Masters and sculpted by Renata Gordon, depicts the Gerber Variable Scale being used to increase a geometric shape by 200%. The shape resembles the State of Connecticut.
Inscriptions around the scale read: "UNITED STATES OF AMERICA," "GERBER VARIABLE SCALE" and "CONNECTICUT."
All program coins bear the same obverse (heads side) image of the Statue of Liberty as designed by Justin Kunz and sculpted by Phebe Hemphill. Obverse inscriptions include "$1" and "IN GOD WE TRUST." 2020 dollars also bear a small privy mark of a stylized gear that is different from the one used for 2019-dated dollars.
Incused on the dollar’s edge are "2020," "E PLURIBUS UNUM" and a mintmark of "S" for the San Francisco Mint.
