The best way to find current values is do conduct a "Completed Items Search" on eBay for knives of the same model and in the same condition as your's. You can see what the actual selling price of the knives was, not just what a price guide editor guesses they should be worth, or wishes they were.
Welcome to Blade Forums!!
And if you want more info on any of your Schrade knives, just do a search of this forum section for the model number. And naturally we'd love to see photos or scans of anything unusual that you might have. And I'm confident the super-friendly folks here in the Schrade Collectors Forum will do their best to answer any additional questions you have.
