Why are such items not sellable?  They may not be worth very much, but
so what?  If you were to offer that half-used box of Cheerios at a stoop
sale, you'd be unlikely to get as much as $1 for it, but if you were to
offer it for 5 cents do you really think it would be impossible to find
a customer?  If you have a willing seller and a willing buyer, even a
half-eaten sandwich can be sold, and would probably fetch a price of more
than a prutah.
