It is known for its cattle market and its souk. Sinaw is considered to be one of the most vital markets in the eastern region of Oman, in addition to Sur Market and Ibra Market. It is an urban city with some rural features, due to the surrounding desert.

Other coins were minted during the Ummayyad Era in the Arabian Peninsula.
