I purchased two fired one in the EE. First $700 shipped ( last year ) and she have seen many rounds.
The second $850 shipped. The second one as been shot a few time. No box or paper.
To have some value..they need to be new -unfired- in original box with all paperwork. That what collector look for, but even then, you will get around a $1000 , maybe a bit more for the right guy.
Not too many US guys have an interest in a Canadian 1867 commemoratives..so collector market for those is very very small.
My guess is that Winchester at the time, made the Commemoratives good looking but skipped on the fit - finish of internal parts. Maybe the thinking is that they will be looked at, more than used as shooter. The 1867 wear a few post 64 stamped parts but those work fine so far. Actions are not smooth. Hopefully with time, as they wear, they will be better.
Barrel are so so in specs..one is .310 and the other .311
Hard to get good accuracy with .308 jacketed bullet. I use cast. The bore of those and others I have looked at with a borescope - all show many machining marks that I would consider defects in modern barrel.
At the end, they shoot well with cast if you take the time to develop load for it. What I like of the Canadian Centennial is the 26 inches octagonal barrel..look good and it is different of the boatload of 20 inches 1894.
