On 30 January 1968 the Jamaican House of Representatives voted to decimalize the currency by introducing the dollar, worth 10 shillings, to replace the Jamaican pound. Coins and banknotes went into circulation on 8 September 1969. From its introduction, the Jamaican dollar has fallen from a peak of J$0.77 to US$1 in its first few years of circulation to a series of new lows exceeding J$71 to US$1 during the first half of 2008. * http://en.wikipedia.org/wiki/Jamaican_dollar
