OK, I understand your logic. My point is that all other types of firearms have continued to be produced since 1985. I don’t see the price of them dropping, despite millions more added to the market. You know a lot more about it than me, but I just don’t see your scenario happening. Collectible firearms continue to go up in value.
In 1980, the Colt AR was a little less than a weeks pay. Today, the Colt AR is still less that a weeks pay. The price really hasn't gone up except for inflation. The full auto on the other hand has gone up 3000 percent because a stupid law makes it illegal to buy new ones.
The 1927 Thompson is a collectible because it is an antique. But what makes it really valuable is because it is full auto and they aren't making them like that anymore thanks to the Hughs act.
Gun prices haven't really gone up much in the last 30 years due to the fact that more companies have entered the marketplace and technology enables guns to be made cheaper and faster. A good accurate hunting rifle cost me $350.00 in 1981. Today a good accurate hunting rifle still can be had for $350.00. The difference is now it's a Savage, then it was Winchester. Technology made Savage the equal of Winchester.
