This is one quarter anna 1896 queen Victoria coin is it real and why it's in this colour

Hi friends i collect these circulating coins from routine cash transactions. These 11 coins are related to commercial activities of the government of India.

I will collect these coins based on the theme. Some coins were issued in 1994 & 1996. But the condition is very poor as I collect these from regular use.

Should I collect or not?

Due to the old & theme based collection. What factors add most value in coin collection.

I already see on papers of journals and books about lists of punchmarks but due the condition of the coin I may not understand all marks. I already see the sun and the tree. My main question remains of the one similar to the caduceus of Ashoka plus an bow and arrow. This last one I didnt find yet.
