i don't know where you guys are at, but it's a tall order to sell field grade (common years ago) sxs's.
Local gun stores want no part of them.
Here we go again!
The fact is, if you take any decent quality vintage or later model field grade double, and list it with either no reserve or a reasonable and realistic reserve on one of the larger internet auction sites, it will sell. Quickly. Not only will it sell, but there will be multiple bids, and it will in most cases realize a fair market price that is higher than the same gun in equal condition would have sold for 20 years ago. Adjust for inflation, and your return might not be much more impressive than a passbook savings account. But you can't shoot or hunt with a savings passbook. Sell it now during a lower demand summer period, and the sales price will likely be less than if sold just before hunting season. That should be obvious.
Walk the same gun around any decent gun show, especially in the fall, and I am certain that you will be approached by interested buyers... even if it is one of those supposedly unwanted 12 gauge guns. Try getting $650.00 for a well worn Nitro Special, Stevens 311, or Fox Model B, and you will likely bring it home.
So if you try to sell that lowly field grade gun for an unrealistic price that is full blown retail or more... and if you think you should get a 98% condition price for a 70% condition gun, then you are not likely to find a buyer. And you can console yourself by spouting nonsense about nobody wanting them anymore.
The same thing is true if you are selling a shotgun, or a Morgan silver dollar, or a truck, or muscle car, or your metal lathe. The prices of many once popular collectibles has crashed. You should be very happy if you bought field grade doubles instead of Hummel figurines or Beanie babies. The oft repeated crash in double shotgun prices has not happened. But just keep on voting for anti-gun Democrats and your doom-and-gloom prediction might come true.
