One Anna 1939 India - Indent Error Coin

I have a rare indent error one anna coin of 1939 from India. The coin is in UNC condition. On the obverse it has several die marks besides that of one anna. The bow tie like mark from the crown of another coin is visible across the nose. A smaller ear can be seen below the ear of George VI. On the nose the word PICE is visible. Below this the letters TIF can also be seen. So strikes of other dies both obverse and reverse can be observed. Can any one make out what other dies have been used on the coin? All this can be observed only on magnification. The coin has a brown mark running across both on the obverse and reverse. Was the mark acquired during minting? This coin is in our collection from 1940's. What could be the value of the coin?
