2000 Canada 5 Cent Error

Recently a 2000 Proof Like 5 cent error was put on eBay with a price tag of $20,000.  The coin was minted with two reverse dies, as indicated on the PCGS slab.  Since, to the best of my knowledge, there is no way for such an error to occur without a little help from some mint employees, it would seem this would fall under the category of a “back door job,” or something contrived by someone inside the mint’s facility – in this case, Ottawa, since it was a proof like coin – and smuggled out.
