From what I've noticed, there are just so many "commemeratives" out there that they have never gained any significant value.
Today I was a a gun show and I've always been looking for a good lever action. The '70s winchester commemeratives are still cheaper than buying a new gun as a shooter. They compare price wise with used contemperary guns, so what did hiding them in a safe for thirty+ years get anyone?
I do shoot a '71 vintage win 64 NRA commemerative in 30/30, it was used when I got it, but hey, I've really enjoyed it as a shooter, and I'm sure that the previous owner did too.
