Can anyone identify, whether this coin has any value ? [opgelost]

Those two images are of 2 Rupees Unity in Diversity - India 2007, Hyderbad Mint.

Can anyone tell whether this coin has any value ?

I'm asking this because I there's a error on the back of that coin.

I will add another normal type of this coin for a comparison.

 First two pictures de-coloured and re-cropped … 

 Showing the reverse error of a large broken die on the left. Value unknown - maybe others know. 

Why is this coin green?  Is it made of plastic?

Errors such as these described as a die break or cud, are curiosities but normally do not add any additional value to the coin. 

Thanks for helping me.

The coin's pictures seem greenish because of the green light I was under, sorry for that. No it's not plastic.

Modern Indian coins are generally very poorly struck, but this cud is quite impressive. A collector of errors might be interested in it and pay a few dollars over the current value, which is probably less than a dollar for a normal coin.

There is no good guidelines for error coin values. Here is what is available on eBay (via picclick). You'll see quite a few Indian coins there. I recommend selecting the largest picture size available (top right).

Some ask for ludicrously high prices for errors. Others try to fool you with damaged coins they are trying to pass as errors. Buyer beware.
