The silver “French Franc” coin is one of the most famous currencies that were circulated in the past in the Arabian Peninsula and the Gulf. It is originally an Austrian thaler known as Austria or “Maria Theresa thaler”. It was first minted in 1741 AD during the reign of Empress Maria Theresa, and its production continued for many years with the same design even after her death due to its spread and people's trust in it for trade.
