DH is right, they are only worth what you can get out of them. If I were trying to sell my older machines, I would look thru Craigslist and see if any were sold that match your model number. Featherweights are highly prized of course, but Coffin cases may not be as desirable due to the amount of space that they take up. I would not go by Ebay, it seems those prices are inflated. At least here in Florida. You might want to consider what you paid for them plus what you put into them and start there.
