In 1883, Kingdom of Hawai'i official silver coinage were issued in the denominations of one dime ("umi keneta" in Hawaiian), quarter dollar ("hapaha"), half dollar ("hapalua") and one dollar ("akahi dala"). 26 proof sets were struck by the Philadelphia Mint and contained the umi keneta, hapaha, hapalua, and akahi dala. 20 proof specimens in the denomination of an eight dollar ("hapawalu") were also struck. The Kingdom of Hawai'i desired to conform to the United States silver coinage denominations and selected the umi keneta over the hapawalu. The silver coins issued for circulation in the Kingdom was struck by the San Francisco Mint
