As mentioned above a lot depends on how it is sold.
Pawn and gun shops notoriously low ball in situations like this, often offering a pittance, and might bait the deal with statements like it is “old”, or no one wants these old 6 shooters anymore, etc and offer 100 bucks.
Private sale is most likely to get the best value, but you have the hassle of offering it for sale ( on line, local gun club bulletin board etc) then dealing with phone calls and arranging meetings to examine, and dealing with tire kickers.
The “easy button” in these situations is to find a gun dealer that does consignments, will list on an auction site like gun broker, or consigning it to an auction house. This usually gets a pretty fair price and is actually what I usually do. Typically auction houses take 20%, but if it is a good auction house that typically does firearms, they generally get top dollar.
I have used an auction house local to me a number of times, and they will likely get let’s say $450 for the gun in this condition. So the seller would get $360.
That is a nice model 10, and I can’t imagine any gun guy or girl not liking it
