1 Dollar from the series American Innovation, Gerber Variable Scale (Connecticut). 2020 year.

The sixth American Innovative 1 Dollar coin in this series, representing Connecticut, the Gerber Variable Scale.

Heinz Joseph Gerber (1924–1996) invented the device while studying aeronautical engineering at the Rensselaer Polytechnic in 1945, a few years after he fled Nazi-controlled Austria with his mother.
The earliest version of the Gerber Variable Scale was made from elastic tape removed from pajama pants. Gerber was the first to create a scale that could bend, expand, contract, and also rotate around an angle. Due to its ease of use and speed of calculation, the Gerber variable scale was a huge success. By the 1950s, it had become a universally accepted tool for engineers and architects around the world.

Obverse: In the center there is depicted, in profile, the Statue of Liberty, to the left of which is the official US motto "We believe in God" ("IN GOD WE TRUST"), to the right - the face value of the coin "$ 1" ("$ 1"). At the bottom of the obverse are the designers' initials "JK" and "PH".

Reverse: In the center of the coin field there is a Gerber scale used to enlarge the geometric shape by 200 percent, and, enlarged with its help, the silhouette of Connecticut. On the left, in a semicircle, the name of the issuing country is minted: "UNITED STATES OF AMERICA", on the left in the center the name of the coin: "GERBER VARIABLE SCALE", in the bottom center the name of the state: "CONNECTICUT". The initials of the designer and the sculptor-engraver are located at the bottom right and left near the edge of the coin.

Edge: Smooth with an inscription (* In God We Trust * E Pluribus Unum * year of minting and mint stamp).
