Interesting fact
The coin , the Harf - al-Mahdi al-'Abbas 1169 (1756) from Yemeni Zaidi State, is interesting because it was made of Billon, which is an alloy of copper and silver. This was a common practice in the Middle East during that time period, as it allowed for the creation of coins that were more durable and had a higher intrinsic value than coins made of copper alone. The use of Billon in coinage also made it easier to produce coins with a consistent weight and purity, as the alloy could be carefully controlled and regulated. This coin is a great example of the innovative techniques used in ancient coinage to create currency that was both practical and valuable.
