Does the value of a shotgun rise with time, in general?
Generally, good quality firearms, that are well maintained and not abused, will track the inflation rate…so they do increase in value. I bought a 460 Weatherby for $1,000 and added a $200 Leupold scope back in 1986. I sold it in 2006 for $2,200. So, I doubled my money in 20 years. However, had I bought a simple index mutual fund back in 1986 (when the DJIA was at 2,000), I would have made more than 6 times on my investment by 2006. Even today, with the bear market, I would be at least 5 times ahead. Firearms are a great store of value and if you enjoy using them, they are a lot of fun. But, they are not the best investments. (Which is why I eventually sold most of my collection.
