I'm no authority on used piano prices, but that is a very nice looking Baldwin studio upright piano. I would not call it rare, or even limited, but that is a good sales pitch. There were probably fewer pianos made with that residential art-case style cabinet, as opposed to the traditional, plain looking institutional 243 Hamilton models, so it could be said that it was a limited edition, per-se., with the internals being the same or similar as the popular institutional Baldwin 243 studio model. So, the only thing "limited" is the cabinetry.
The piano is very attractive, and looks well cared for. If the internals are as nice as the cabinet appearance (and only a qualified piano tech can tell you that for sure) I'd say the piano is definitely a nice find. I am a big fan of the Baldwin/Hamilton 243 studio model.
In terms of price, you can find the regular Baldwin 243 studio models in decent shape anywhere from $500 up to $2000+, depending on the location and the seller. Dealers may ask twice that price, depending on the dealer.
As far a suggesting a ball-park price, it depends on how much you like it and want it. Doing a quick Google search, I saw a few in that age range from a low of $2500 to a high of $5500. The thing is, when you start getting into the $5000 price range, you can get a taller, better sounding piano.
If the price is less than $5000 it might be worthwhile, if in good condition.
Again, my comments are my own and just my unsophisticated .02.
