The problem with any appraisal on your knife is that there is no way to benchmark it. How many of these have sold on e-bay since they were made? Everyone's input is going to be a WAG. I would suggest to go ahead and get some inputs and then come up with a "reserve" price for an e-bay auction that you would be overjoyed to get if it sold. If it sells for that or more, then it's all upside. If it doesn't, then you will know it's market value and you can put it up again with a lower reserve. The only downside is e-bay's fees that you'll pay for setting a reserve price. IMO this is (1) cheap insurance against not leaving any money on the table and (2) a reasonable fee for learning it's real market value. If you do put it up on e-bay, try to include a pic of the thinkness of your knife vs. a standard 14.
