While prices went way up during Covid, they seem to have dropped down quite a bit to what I would consider normal again. Personally, I love the Morse machines as being easy to work on as well as easy to work with. I have a Remington which is virtually identical mechanically but not as zippy in style. Typically they do the straight stitch for quilter-use very well and can handle heavy duty sewing like multiple seams or heavy fabrics like upholstery. The aqua color is a plus, some people like them as decor pieces. I'd say no real benefit or extra income on the stand, it can even be a negative -- a lot of people may have room for a sewing machine but not the cabinet.
My estimate in the Seattle area (where I just moved from) would be only $20-40 dollars at garage sales or thrift store prices but again, you never know.
When putting it up for sale, having the attachments and/or maybe even a manual can be a huge plus. You should include a picture of the throat plate (where the needle goes in) and any accessories you have for it (plates, feet, etc.). Having both the straight and zigzag throats and feet can make a big difference.
