How rare is my Submariner

[JopsonsCarlisle1960]

I recently purchased a Rolex Submariner 16610 - Black / Black (c)2003 stainless steel, all original box and papers.
The difference with this Watch is it has 2 yes TWO set of original Rolex guarantee papers dated from the purchase date both stamped from Rolex with the Watches serial number.
I have spoke to a couple of serious Rolex collectors that have both expressed interest in it for their collection and I have turned down offers they have both made until I get some more information / views on just how rare and valueable this example may be....
Does anyone know of any other Rolex Watch with a set of 2 punched paperwork from Rolex original?
The more feedback the better so please get in touch.
