Half dollar

The term "half dollar" refers to a half-unit of several currencies that are named "dollar". One dollar ($1) is normally divided into subsidiary currency of 100 cents, so a half dollar is equal to 50 cents. These half dollars (aka 50 cent pieces) are denominated as either Coins or as banknotes. Although more than a dozen countries have their own unique dollar currency, not all of them use a 50 cent piece or half dollar. This article only includes half dollars and 50 cent pieces that add up to dollars and are in the form of a coin.

Notes
  1. Some countries have had many varieties and forms of half dollars/50 cent pieces. The dates used in this table reflect when the current form (design/metal base) was first issued.
  2. Half dollars from this country no longer circulate as they are minted in small amounts for collectors who purchase them at a premium
  3. These half dollars were also accepted as legal tender by the successive Provisional Government of Hawaii, and Republic of Hawaii governments.
  4. These coins were used until Hawaii became a U.S. territory in 1900
  5. While 50-cent pieces have been discontinued in Taiwan, they are still legal tender.
