Title: Jamaican dollar
Content:  The Jamaican dollar (sign: $; code: JMD) has been the currency of Jamaica since 1969. It is often abbreviated to J$, the J serving to distinguish it from other dollar-denominated currencies. It is divided into 100 cents, although cent denominations are no longer in use as of 2018. Goods and services may still be priced in cents, but cash transactions are now rounded to the nearest dollar.

All the other dollars in the vicinity either began on the US dollar unit, in the case of Belize, Bermuda, and the Bahamas, or the Spanish dollar unit in the case of the Eastern Caribbean territories, Barbados and Guyana. The Spanish dollar unit at any rate was approximately the same value as the US unit.

Content:  Jamaica used both sterling coinage and sterling units of account from 1840 until 1969. But unlike the rest of the British West Indies, Jamaica had its own special varieties of the sterling copper coinage. Apart from a Bahamas penny of 1806, and the four pence (4d) groat coins that were specially minted for the British West Indies, and later for British Guiana only, the rest of the British West Indies just used exactly the same coinage that was circulating in the United Kingdom. When Jamaica went decimal in 1969, the new Jamaican dollar was in effect a half-pound. Jamaica and the Cayman Islands were therefore the only territories in the British West Indies to continue with a descendent unit of the pound sterling. (See the main article at Jamaican pound.)

Jamaica was the only British West Indies territory to use special regional issues of the sterling copper coinage.
