2021 American Innovation 1 Dollar Coin: Virginia, Chesapeake Bay Bridge and Tunnel

 [Product Description]
 This is an American Innovation $1 coin issued by the United States Mint in 2021. The coin features the Chesapeake Bay Bridge and Tunnel, a representative example of innovative architecture in Virginia.

 Opened in 1964, the Chesapeake Bay Bridge and Tunnel is a massive transportation complex connecting southeastern Virginia with the Delmarva Peninsula. Its unique structure, combining a low-lying bridge, an underwater tunnel, bridges, a ramp, and an artificial island, makes it one of the world's leading bridge and tunnel complexes.

 The reverse side features a design that depicts the structure of a vehicle moving from the sea road to the tunnel in a cross-sectional view. It symbolizes the advanced civil engineering technology and ingenuity of the time used to combine the bridge and the underwater tunnel. The words "UNITED STATES OF AMERICA" and "VIRGINIA" are engraved around the outer edge.

 The surface features a sideways depiction of the Statue of Liberty and the denomination "$1". The series' common gear-shaped mark, symbolizing industry and innovation, is also engraved at the bottom.

 This is one of the "American Innovation $1" series, which showcases representative inventions, scientific and technological advancements, and groundbreaking events from various states and regions of the United States. It's also recommended for anyone interested in American history, transportation, architecture, or civil engineering.

 Although this coin has a golden appearance, it is not a gold coin. It is legal tender of the United States, manufactured from a copper-based alloy.
