Shoot it! I bought a NIB 1995 Jap inv+ light 12 a year and a half ago and went through the same thing, I knew I could put it on gunbroker and double my money easily, but at the same time I had never had a New Auto-5, so I really wanted to shoot and hunt with it. I justcouldent get over the idea of harming it's collectability. My solution was to put a sling stud in the buttstock so as to destroy collector value, while at the same time making it a more effective hunting gun, and loosening myself up to the idea of treating it like a "regular" gun. A New A-5 is a thing to behold, they arent making anymore of them. Life is short, enjoy the gun.
