I see, so it's basically this card without the serial numbering? If that's the case it sounds like you have a card that either missed the serial-numbering part of the printing process and was accidentally packed out/released, or it was one of a group of extra unnumbered copies that manufacturers sometimes set aside for replacements, and then it found its way to the market through unofficial means (sometimes referred to as "backdooring").
In either case described above your card doesn't qualify to be listed in the DB (please see the FAQ entry about wrong back cards as this is a somewhat similar situation) but you can still note it in your own collection. Some collectors place a premium on that kind of item while others ignore them, but regardless it's an interesting card!
