If I was to hazard a guess it is probably a homebuilt piece of furniture from a farm.
The boards on the door appear to be pine and about 12" wide or so(?) and the construction method certainly doesn't suggest someone who was a cabintermaker by any means. Even a neophyte cabinemaker would have framed out the door and then had an inset panel- to call the doors primitive would be an understatement. it looks like someone looked at a fence or barn door and roughly copied it. In fact, my guess is that it was built of salvaged wood from a barn or similar strucutre- did you find any animal hair, hay, or other similar stuff wedged into the rough grain? Check on the underside boards and places where it would have survived a bit of cleaning and that ought to give you an indication.
Some other intersting details are the angle baces under the projecting top- you can see how they don't really do anything structurally, but are more aesthtic in purpose. Of course, if someone had an apple peeler a canning press on the top I bter you wouldn't want the front lip breaking off! Another interesting detail is how the center stile between the doors is notched into the stile underneath the top. You will also note how the doors project lower thatn the center style. A bit goofy, but gives it that rustic look that probably caught your eye in the first place, eh?
The catches are a very common type from around the turn of the century- I grew up in an old farmhouse and they are the very same type that was on all the cupboards in the basement (which had originally been the kitchen cupboards before my dad remodeled the house). The hinges are probably of the same age.
I wouldn't think it would have any real "marketable" value as in being historically signifcant, i.e. you won't be gettig milliions on the Antique Road Show. Where did you get it?
