I have to completely disagree with the after-shooting value opinion of the previous post. ANY excellent condition 94 of that vintage is worth more than that, let alone an octagon barrel rifle. I think you'll realize at least what you paid for it after shooting it, or close to it if you keep it in perfect condition, though fired.
Few of the commemoratives have really taken off in value. The primary value of them is as shooters, and most of the rifles with octagon barrels shoot pretty well. I've shot several of them, from new/unfired, and never had a huge loss of value. Many of us value them as shooters above collectibles, and a gently used one will still bring pretty good money. I'd prefer to buy a used one over a new one, but would have zero qualms about shooting a NIB gun like yours. Pretty much any new gun you fire will realize some loss of value, but that's part of the game, I buy them to shoot. Hold on to it a while, and you likely wont lose any value anyway.
I still see Canadian Centennials and similar commemoratives for $500-$600 range for NIB at the Winchester collectors show, at least as recently as a year or two ago. Sometimes they are priced higher, but I haven't seen them move much when priced higher. Online or in some areas they may go a bit higher.
