I wouldn't say that you missed any kind of a jackpot. It is certainly a scarce model, but not a model that was seemingly ever in high demand. Basically, it is a 5904 that is DAO. In other words, it is a full size 9mm double stack with alloy frame and no levers on the slide as it is a pre-cocked DAO.
Good pistol. Now if it was 98%-100% NIB with the box, then yep, it's certainly got some value as a "collectible", especially for those looking to have NIB examples of the irrational number of 3rd Gen model variants. This one is a scarce variant.
As a 70-80% shooter or carry gun, it would be a good one for those tasks... at maybe $350.
