Commemorative coins, commemorative guns, whatever ..... they have some intrinsic value, but once put into use, become just another used item.
The Winchester NWMP commemoratives and the Canadian Centennial models are cases in point. Interesting wall hangers, but ..... once fired, less valuable than my VG+ pre-64 '94, particularly if they don't come with the original factory box.
I had the same decision to make when I acquired my Uberti 1 0f 1,000 - keep it as a wall hanger or shoot it and enjoy it. I'm not able to own guns that I cannot shoot. Not sure I'd really want to.
An acquaintance 'invested' in a top quality British Mauser sporting rifle in .275 H&H (7mm Mauser). He couldn't bring himself to shoot it and even when he posted it for sale at considerably less than he paid for it, he couldn't move it. Basically, he's stuck with it, so he might as well enjoy it, IMHO.
Life is too short to shoot ugly guns, date homely women, eat domestic MILK chocolate, drink cheap beer, wine or whisky. Lord knows I've done a lot of those, but now I know better .... ;>)
