Who would have thought that a double-barrel shotgun made in 1955 would be worth nearly $100,000 today? http://www.gunsinternational.com/J-Purdey-Sons-Best-Over-Under-20-bore.cfm?gun_id=100043825 It's only 55 years old-- that's not an antique in the world of firearms! But it's a Purdey, and one of the upper-end models that probably cost as much as a good used car back in the day. I would never have guessed how much this thing would be worth, if I had not just seen some ads on the internet (I know some people ask more than fair market value, but there's plenty of evidence that many Purdey shotguns sell in the 10,000 - $50,000 range. If I ever see one for sale at a yard sale, flea market, or little hole-in-the-wall pawn shop for around $300, I'll be sure to pick one up !
