Unless you save an ad it is hard to say how many times a gun has been relisted following auction end without a bid. Still best to review closed (sold) auctions. But only GB has that feature as far as I know.
A LGS has a 1941 Deluxe on consignment for $1250. Thin blueing on receiver and muzzle and the checkering is really worn. He has had it for 3 years. I offered $1100 out the door but he isn't interested. He didn't even ask the owner.
I say ask what you want and you can decide how badly you want to sell.
Markets fluctuate. Marlins (JM) were bringing crazy money. Now the Rugers are out and the quality is really good so Main prices seem to be dipping.
