Depending on where you are located.
If you live in an area with quite a bit of cycling, I would say that almost any $10 Ross bike is worth buying for resale at $10 each. Especially if it looked like the chrome would clean up well.
If you have storage room, I would suggest buying them at $10, cleaning, lubing and getting them ready to sell in the Spring. Possibly even do touch up paint if they would match easily... and then pricing them to sell with a little wiggle room for negotiation in the spring.
You probably wouldn't get rich with them, but depending on where you are... If you are in New York or another hot market, you might even get $100 for them if you get them ready to ride and looking nice.
