Yours was either:
1 - One that got into packs that missed the serial stamper - printing flaw, not catalogued here
2 - An extra that was kept by the manufacturer in case one was returned due to damage and was released during a bankruptcy liquidation (also known as "back-doored") - not eligible for inclusion here
