This study examines the coins, weights and measures used in the Gulf region during the seventeenth and eighteenth centuries, as the region attracted traders from different nationalities during this period: Portuguese, English, Dutch and Indians. Some local people and people from the surrounding areas, such as Arabs, Persians, Turks and others practiced commercial activities in the region. Of course, all of them were paying for the goods they buy, which made the region teeming with different types of coins. That, in turn, made it somewhat complicated for researchers to find out the exact value of those coins, as well as to determine the time periods during which those currencies came to the region or for how long they were in use in commercial transactions. Despite the fact that the weights and measures that had been used in the region during the study period were varied, changing over time, and influenced-positively or negatively-by the surrounding states and countries, but we can talk more confidently thereon than currencies which were exchanged in the region.It's worth mentioning herein; that many resources, references and reports, that have been referred to herein state many currencies and measures which had not necessarily been used although it was existed, also there were currencies, measurements and weights that were not mentioned therein.
