My girlfriend runs estate auctions and she is selling the stuff so she wants the most for the seller obviously but she doesn't know much about these older bikes which is why I asked here for her. Someone has already told her (word of mouth) they will take the girls bike for $100 (it is mint) and we figure we should be able to get at least $100 for the boy bike. The sale is not a normal yard sale, there are many vintage/collectible things there so it will be attracting the right people to bump the price up above your average yard sale.

On a different topic, I have a Bianchi Special 12 speed I purchased in '83 that I last rode in 2004 (it is hanging in my garage). Is there any value in this bike? It is all pretty much stock but in used shape. Thanks.
