Mule Of 2 Observe Dies NZ 5 Cent

If anyone wonders about "what a Mule Mint error is?" check it out here:
http://en.wikipedia.org/wiki/Mule_(coin)
this type of coin also has another form of name , most of the time called a "double head" if it has 2 of the same observe or "double tail" if both parts are the reverse of a coin or in this example it could be called a " 1974 NZ struck with 2 Observe dies".

I couldn't find any other examples.

Heh, I would be deathly afraid of it being a garage job as NNC is not an actual TPG(self-slabbing seller) and should not be trusted for grade or authenticity.

NNC don't have issues with Authenticating a coin being genuine or not but they do have issues with grading and that is a fact.

I haven't received it yet and exactly what I was thinking of doing, however, I was also thinking of just sending it back for a refund, I'm not too proud of the slab and NNC won't refund you if you pop it out the slab. By the looks of it, it may very well be about unc but I'll just have to see it with my own 2 eyes and than I'll decide to return it or not. It's a bit scary purchasing coins from them ,I am well aware that they grade their coins by at least 5 or 7 notch up but what I'm really afraid of is if it's genuine and that I can't tell unless I take it out of the slab and see it for myself so this one I kinda regret of purchasing. I probably will send it back.

Sorry, I had assumed that this was a varified error already with possibly other examples known. Try and work out a deal with the seller to allow you to examin the coin out of slab and send it back if you find that it is a counterfeit. It's always worth a try; some sellers are truelly understanding. I'm not sure how this works if you do return it, with weird ebay rules and all, but it would be worth looking into.
