I have found, over the years, that most small wheeled bikes, like yours, have little value, even when they are in very good condition. Your bike is not in good condition and, though I do not mean to offend, it is worth very little. For example, I managed to get only $10.00 for this vintage BSA and it was in very nice shape...
These days, I donate any small wheelers to a local bicycle salvage and share organization - Bicycles for Humanity.
