Not to sound crass, which it probably does, but worth only what somebody might be willing to pay.
Much better known scopes are selling on Ebay for peanuts.
I recently bought an older Bushnell Sentry model in mint condition for the starting bid of $13 since i was the only bidder.
Now think about this, the guy had to pay ebay for selling it, then ship it to me, so was it even worth the trouble?
I would just keep the scope, use it for bird watching, or maybe even on a trip to a beach or somewhere, it could be usefull.
I even keep a small one on my boat for spying on other anglers. If their hanging in one spot very long, i wanna know why.
Get a car window mount for it on ebay, and keep it handy, you might be glad you kept it.
