This one is made of Nickel-brass alloy and was circulated from 1957-1964. It has a diameter of 17mm. This one paisa has the four headed lion symbol at the obverse, and one paisa and date on reverse. We can also see "rupaye ka sauvan bhag" in Hindi which means 1/100th part of one rupee.
The one pice or one paisa with the hole was circulated circa 1940s . It has one pice or paisa written in English, Hindi and urdu. And on the other side there is a sort of brocade or design. This would have been minted under George VI, who was emperor of India at that time. I believe that the crown represents the king George VI so the the crown, date and denomination are on the obverse and the design is the reverse.
