British India Coins–Average Condition

What is the average condition of available British India Coins? I have made some experiment in this direction. I have collected a hand full of British India Coins from various sources. Picked the coins at random and keep away the shabbiest and illegible coins. Sorted the coins into copper and brass coins and copper nickel coins. Below I have given two photos. Please watch them and come up with your comments.

Some copper and brass coins are blackened. Victoria coins are difficult to find in good condition. East India Coins are of decent quality!
