Coins have always been a constant necessity in the history of mankind.
Since ancient times, human beings have changed valuables, bartering, sales, exchanges.
It all begins with the use of precious metals that are scarce in Nature, that is, we go back to Mesopotamia around 2500 BC.
In Al-Andalus, the territory of the Iberian Peninsula under Muslim rute, one of the primary activities was trade, and trade was possible thanks to a universally accepted currency.
At first, the Muslims usted the currencies of conquered territories, the Visigothic currency; but thanks to trade, Abbasid coins from Syria began to arrive, together with Unmayyad dirhems.
Currency minting in Al-Andalus began with Caliph Abd-Rahman I and became widespread with Abd-Rahman II in Córdóba, where the mint used to be.
The war originated between the Caliph Hisham III and its Prime Minister Almanzor, unleashed the fall of the Caliphate, especially dut to the great discontent among the population, when the Caliph collected more taxes to finance the fighting of Almanzor. There was a great devaluation of the currency, the Dirham with less than 20% silver and sometimes even minted in bronze.
The currencies in Islam is a true historical document that gives us valuable information, since it is a written documentary source with epigraphs on both sides of the coin.
Islam has discouraged the use of human figures or animal representation to avoid possible idolatry, which has made the Islamic world a decoration based on words.
Whereupon, coins have become a very importan and valuable source of information.
In Al-Andalus they have used gold coins called gold dinars, silver dirhams and copper felus.
Thus the coins have religious and political messages, messages the uniqueness of God, Allah and his prohphet Muhammad, messages of the political governors, with their names coined in them, and thus be able to legitimize their power.
In Al-Andalus there were mint in Almeria, Malaga, and the most important, in Granada.
In addition, is is known that the citadel of the Alhambra had its own mint, as evidenced by some epigraphs found in coins, which, from the reigning Sultan Muhammad V, will be inscribed with the name of the mint where they were made.
In the Nasrid Kingdom of Granada the coins bear the motto of the Nasrid dynasty, “there is no victor but God”. The purity of these coins is incredible, since the gold dinar or gold doubles reaches 90% purity, and the silver dirham up to 95%.
