Personally I wouldn't shoot commerative guns. I also don't care to collect them so if I were in your situation I would find something I really wanted and put out a WTT or sell it outright. Unless you gain a personal satisfaction from owning it I would say get something you really want. Someone out there would likely pay good money for the 1st of a set.
I have had the same "problem" this week. I have a 1 of 5xx Springfield 1911 that I won at a Friends of the NRA banquet about a dozen years ago. Right now I'm short on 1911's and I decided to get this one out and start using it. I has some gold "bling" that I would rather not have, but......
If the piece is a collectible, then shooting it would remove the gun from the collector's want list. If it is merely a gun which has not been shot, then go for it. In the end, it eats nothing and costs nothing to leave lie in the safe... but shooting it could cost dearly.
Even though this pistol has been a safe queen I've been thinking about shooting it. I don't think it really has that much more value. All my guns are keepers, I've got some that I've haven't shot in many years.
If I decide to shoot it I think I'll add a adjustable rear sight & get a .22 converson kit for it. I'm stuck, I want to leave it unfired & I want to have all kinds of fun shooting it.
