My neighbor has either an 1800's or 1900's singer sewing machine
It has 7 drawers... three on each side and one longer in the middle
It is mahogany and is rally nice...
It is similar to this one but does not have the inner corners in the middle and slightly darker... we want to get rid of it and would like to know what its worth

That is the exact one that I have.
You need to find a collector or someone that really wants it.

If you take it to an antique dealer they will tell you it is only worth sentimental value and offer you five or ten dollars and turn around and sell it for $150. In the mean time they have junky ones they are selling for a hundred or two dollars that aren't near as nice.

I would try and sell it for $150. And don't take less than $100.
