where on the web can i find old guns and thier values?

It's going to be tough to find actual values for your guns on the web. What you can do is look at websites like www.gunsamerica.com and www.auctionarms.com and see what similar guns are selling for. If the guns are yours and you're interested in finding out their value, I suggest going to Barnes & Noble or Borders Bookstore or whatever large national chain book seller is in your area. There you should find in the hunting or firearms section The Shooters Bible or another type book that comprehensively lists guns and their values. If you're not averse to taking the guns to a gun dealer, I would do that and ask them what the replacement value might be for insurance purposes. They will tell you a figure that they might sell them for if they were sold at retail. Keep in mind this is not the amount they would pay you if you wanted the gun dealer to buy your guns. It's better to sell them yourself for something close to but slightly less than the retail price.
