I've read some reports that they (commemorative models) make OK shooters.
Some guys have had pretty crappy luck with them too, seemingly because of pretty low Quality Assurance at the manufacturer, thought to be related to the theory that 'nobody is going to shoot it anyway'.
It's worth whatever you can get for it, in the long run, but unless it's still pretty much giftwrapped from new, it's not that collectible.
