If it was new in box, with box and papers, never used, sharpened, or carried, and you threw in the sheath (which are still made and cost about $12 new), you could probably list it on the 'bay for $80-ish and hope for some higher bids. A few sold for around $110. Just dig around in the completed/sold listings using the model number and description. If you put it up for $60 it would probably sell for sure, just not sure how much higher than that it would get.
You can try it here on the Exchange and save the E-bay fees, but of course you have to pick a price and hope you got it right versus let bidders set the price.
Keep in mind, these are just my observations and opinions. I am not a Case Hobo collector and don't know the relative rarity or desirability of that particular model. Maybe wait for others to chime in before making any decisions if you were looking to sell it. For insurance or estate valuation purposes, maybe $120 based on what it would possibly cost you to replace it if you had to find one on the open market today.
