I found one on sale last month at
https://www.shopgoodwill.com/auction...-37184215.html. It was going for $9.99. That being said, value of machines varies by region and demand. Think what a willing buyer would pay a willing seller and keep in mind that sometimes they cost more to ship than the value of the machine. If it's something you are using yourself and you enjoy sewing with it, it could be priceless.
