Rare does not always mean high value, 600-800 dollars. There is just so very little interest in non big four or big five double makes. Same gun, if made by Smith, would have ten interested buyers on a web auction. Many times when there is just no interest by multiple bidders then prices are just never going to be that big for secondary makers like Aubrey, Baker, etc.... That said I expect the gun to sell for well under a grand. If a Smith it would bring two or three times as much. Market price is what it is. If you pay much more than that you might have a problem sellng it later for what you have into it. But if you love it and money is not the issue search gunbroker and other sites. The average selling price for the gun you describe will be under a grand. Now you can find asking price guns much higher but a few of them have remained unsold for multiple years.
I just bought a 53 in very nice shape, 50% case and very nice wood for $400 dollars. Only complant I have on the gun is someone put an ivory mid bead 9" down the barrels. I don't like extra beads and none that close. Removal and tender filling in the hole will make the gun much more usable. Maybe it's in high condition because that bead has bugged all the owners so much they never shot it.
