I spend quite alot of time on GB and IMO a hidden reserve turns most people off. Man up and list the gun for the minimum price that you'll take for it and don't play any third grade guessing games. It seems that if a guns reserve is a little higher than anticipated it will not meet the reserve and get stale real fast. I've seen many guns listed with a hidden reserve or a high base price not get any action and not sell (or the sellers who list the gun with a reserve and then say what the guns reserve is in their description:shot. The seller then relists it at a $0 or very low starting price and people get auction frenzy and the gun ends up selling for more than the opening bid that never got any hits. I personally won't bid on any gun with a reserve.Your listed price definitely scared me off. You bought the rifle at a pawn shop correct? If so then you should have a general idea how much it's worth. Most pawn shops I know have multiple books to help them determine the value of a gun so I doubt what you paid for it is far off what somebody else might be willing to pay. I think you have to figure out how rare it really is and how much of a demand there is out there for it and then how much money you want to make off of selling it to members of MO. If you really want to find out what it will bring list it on GunBroker with a reserve and see what happens!
With that being said this is a real odd ball and would be a really neat piece in a Marlin collection and I can obviously see the sellers pov. It is really nice to have a site like this to "test the waters" per se and see what the interest is at their starting price w/o any listing fees.
Awesome gun and good luck with your sale.
