If JJ buys it, puts it on Gunbroker, sets it for no reserve, starting price $.01 and he carefully times the auction to start and end during the middle of prime-time evening hours through all time-zones of the U.S. He'll probably turn a profit. I'd say the odds were well better than 90%... however, it's not a certainty.
I'd set it to start and end on a Wednesday, around 8pm CST. Pay the extra $.50 or whatever for a picture, premium listing, bold color text. Say NO RESERVE in the description.
I've never done worse than a fair market price for everything I've sold on Gunbroker this way. Although I had to be prepared for bad luck and someone bidding $50 or something, and I'd have to honor it. Although if you look through Gunbroker, there's about 99 reserve auctions that end with no bids, for every no-reserve one that has 10 or more bids.
