Many persons living in Jamaica today are only familiar with the decimal currency or 'dollars and cents' system which is used in trade for goods and services. Therefore, it is hard to imagine a time when this was not the official currency of the island.

However, with the eradication of the Tainos by European exploitation, Jamaica was introduced to the currencies of several countries, which were all used at some point in time.
