alan2here Posted May 29, 2009 Author Share Posted May 29, 2009 Sorry to say coloring in a coin dosn't tend to work in a convincing way. I don't know what they are made of. Link to comment Share on other sites More sharing options...

iNow Posted May 29, 2009 Share Posted May 29, 2009 I am actively disinterested in this topic, but thought it a simple enough answer to find as pertains to composition. Nifty chart... right there... go figure... at wiki. http://en.wikipedia.org/wiki/Indian_rupee#Independent_Issues.2C_Decimal.2C_1957- Which leads to a pretty darned useful site over at the reserve bank of India: http://www.rbi.org.in/scripts/ic_coins_5.aspx Link to comment Share on other sites More sharing options...
