Above are some 5 rupee coins minted in the year 2009 by various mints...

---*--- First and second coins are minted in Hyderabad mint with different fonts.. clearly visible in above image..(see the digit '9' in '2009').. can any one tell if its some variant coin or error coin ?

---*--- third and sixth are Kolkata mint coins with difference in printing.. in 3rd coin all prints are more sharper.. where as in sixh coin all images and text have very smooth and blurred kind of edge as clearly visible.. 

can any one tell if its some sort of error or what ? its not double strike error for sure..


---*--- fifth coin is a off-center non planer error coin of kolkata mint with same smooth printing as of 6th image.


--*--- forth is a mumbai mint coin


Can anyone tell me if Nodia mint printed these coins ? and did any other mint also printed the same ? Is ther any more varity in these coins in 2009 ??

Also can anyone tell me if the coin was minted in any other material other than Brass ? was any Cu-Ni version minted ?

Is the sixth coin in the image made of Cu-Ni ?? How to find it out ?

Good observations about the variations in the same mint!! May be two different sets of dies were used(or may be one of them is a fake)

Try weighing them if you think they are made from two different metals.

@broken Compas :Hmm.. need to arrange one precise digital weighing machine for that...

Materail of first 5 coins seems to be Brass only so I think no one will mint fake coins in brass as it will cost them too much...

According to Krause, reserve bank of India and Wikipedia there were no 5 rupee coins minted on Brass. All of them are Cupro-nickel. The color of the coin is not an indicator of the metal used, it might very well be just toning. Why do you think it is brass?

As per above link new Rs.5 coins are made of nickel and brass, which is an alloy of copper and zinc. This is why the coin color is more like brass and I got confused...


And due to differnet proportion of brass and nickel the coin color varies... and there is no any toning done..

I see! Got to coerse someone from the mint to join the website.. They should be able to answer a lot of questions! 

But again we can't talk smack about the Indian mint if we did.. :)

@PJ: 2009 H mint varieties are known as die varieties. As you already observed, "9" is different. Also mint mark sizes are different.

For Calcutta mint coins varities, I've seen many B and H mint coins fro the same year with difference in quality. it would be manufacturing quality variation or some of the coins just went through more ware and tear than the other.

5th coin is a off-center strike error coin. Good to find that one. And yes, these are all Ni-Br coins.
