you won't get a very good price as a job lot because people are only prepared to pay for what they want in the collection they won't want to buy what they have alredy, so nobody is going to pay the full value. It would be best to sell them as small units of the same interest area. Make the auction deadline on a weekend evening pref. sunday as most people are at home then. Choose a 10 day auction so that people have 2 weekends to find them. If you have any idea of their value put them on at a fixed price puchase because you can put them on for a lot longer and people will have more time to find them and make up their minds
