I have a Mossberg 500A 12 gauge with a gold trigger and flowery engraving on the side of the receiver with wood stocks. Were these valued any higher than a standard 500? I'm sure it's not super rare, but I really haven't used it much in the 12 years I got it (maybe 200 rounds). I'm starting to get back into shotgunning, and I was thinking of picking up another 500 or maybe 590 and leaving this one in the safe. How many of these were made?
