Salam, I had to revise history in regard to who was the first who made the islamic coin. Sunni scholars claim that it was Abdul Malik bin Marwan. There is a narration that mentioned that the caliph summoned the imam al baqir from Madinah to ask him about it so imam baqir told him to change the roman coins to islamic coins. Shia scholars say that Imam Ali was the first who made the islamic coin and that imam sajjad, not al baqir, who was summoned by abdul malik and he told abdul malik to revert the coins to the way imam ali made them. Shia scholars also say that Mo'awyiah was the one who changed the islamic coins by imam ali to the coins of persia. what do you think? https://www.islam4u.com/ar/maghalat/ضربُ-النقود-في-الإسلام
