Hoover Dam:

The Hoover Dam is one of the most impressive engineering structures of the 20th century. The monumental dam was built in the 1930s on the Colorado River and connects the US States of Nevada and Arizona.

The Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the boundary between the U.S. States of Nevada and Arizona. 

Constructed between 1931 and 1936, during the Great Depression, it was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over 100 lives

Bills passed by Congress during its construction referred to it as Hoover Dam (after President Herbert Hoover), but the Roosevelt administration named it Boulder Dam

In 1947, Congress reinstated the name Hoover Dam.

The Construction:

Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water, and produce hydroelectric power. 

In 1928, Congress authorised the project. The winning bid to build the dam was submitted by a consortium named Six Companies, Inc., which began construction in early 1931

Such a large concrete structure had never been built before, and some of the techniques used were unproven

The torrid summer weather and lack of facilities near the site also presented difficulties. 

Nevertheless, the dam was turned over to the federal government on March 1, 1936, more than two years ahead of schedule

Hoover Dam impounds Lake Mead and is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 30 mi (48 km) southeast of Las Vegas, Nevada. 

The dam's generators provide power for public and private utilities in Nevada, Arizona, and California. Hoover Dam is a major tourist attraction, with 7 million tourists a year.

The heavily travelled U.S. Route 93 (US 93) ran along the dam's crest until October 2010, when the Hoover Dam Bypass opened.

The Coin:

The Reverse of the $10 (Ten Dollars) Silver Proof & Coloured Coin showcases this world-famous building in an extraordinary way. 

The striking shape follows the characteristic silhouette of the Hoover Dam and gives the motif a particularly realistic and imposing effect. 

The detailed colour scheme shows the mighty rocky landscapes of the Black Canyon as well as the monumental dam wall in an impressive perspective.


The Obverse of the $10 (Ten Dollars) Silver Proof & Coloured Coin depicts a historical account of the construction work and is a reminder of the enormous engineering feat and the thousands of workers involved in the construction of the Hoover Dam. 

The finest details and different relief levels give the design additional depth and dynamism.

The 2 oz silver coin impresses with its unusual shape, the detailed ultra-deep relief and the strictly limited mintage of only 500 pieces worldwide.
