Prices are seasonal and any Fisher Stove is worth what buyer and seller agree upon. Without a picture of the entire stove it's difficult to determine what you have. It looks like angle iron legs, which means it won't have bent corners made from one piece for the box. Bent corners would be a UL Listed stove. If it has a UL tag on the back, they are worth more, since most jurisdictions and insurance companies require it. It was made after 1980 when they were listed, but GA along with many others offered any stove built in the old configuration with angle iron corners as a cheaper alternative. They were normally used on a hearth where shields are not required. If yours has bent corners, it will have removable legs and rear and bottom heat shields. The tag would be on the rear heat shield.
The states that require all stoves to be EPA Certified normally sell for less. (WA, OR, and CA)
That's a good size stove for your area and should be desirable since you require much less heat than here in the north where Papa is at a premium and hard to find. Watch Craigslist in your area to get an idea of selling prices. You will find anything from $100 to 1000+ on eBay. Surprisingly sooner or later they sell overpriced in my opinion. A rear or side vent is more desirable for most installations on a hearth where the pipe needs to be low under the mantle. Brick condition, paint, and moving parts wear are other factors to consider. Most any of these stoves can easily be brought back to like new condition to sell for the premium price when reconditioned.
We should be able to determine who made the box with a picture of the stove bottom initials. OK, so I need it for my screen saver too.
