Q. The copper coin (shown below) was first introduced by Sher Shah Suri during his rule of India between 1540 and 1545, along with Mohur, the gold coin and Rupiya, the silver coin. Later on, the Mughal Emperors standardised the coin along with other silver (Rupiya) and gold (Mohur) coins in order to consolidate the monetary system across India. The question is, which english phrase originated from the name of this coin.
A. The coin was called the 'Dam' (pronunced daam) and the English phrase “I don't give a dam[n]″ originated from it due to its small worth.
