An Old Gear Head's analogy-
I get asked this all of the time. I see sewing machines a lot like a car. No dealership will tell you the value of a car just by a description. If you send them a picture it may help slightly, but until they see it in person, test drive it, and see how much wear and tear it has, if anything is missing or broken, there is no way you can put a value on one. AND some cars are worth more in different parts of the country.
My example-
I have a 78 Cadillac. It was my grandmother's car. What is it worth?
The description may sound like it looks like this,

But it really looks like this.

When you tell them what it is worth they say, "But it's a Cadillac". And "It was my grandmother's car. She used it all of the time."
Now, replace the word Car with the words Sewing Machine, and Cadillac with the word Singer.
I hear it all of the time.
