In early September the Central Bank of Ireland will issue a Proof €15 silver coin commemorating Irish-American John Philip Holland, inventor of the first modern U.S. submarine.

USS Holland (SS-1) was the United States Navy’s first modern commissioned submarine, and is named for its Irish-American inventor. The boat was originally named Holland VI, and launched on May 17, 1897. The submarine was officially commissioned by the U.S. Navy on Oct. 12, 1900, at Newport, R.I.

Holland also created the first Royal Navy submarine, the Holland 1, and is widely regarded as the father of the modern submarine for his designs.

No details of the coin's design or specifications are available.
