Patty, as Dock said, your sets would be worth whatever someone is willing to pay for them. The Red Book values are pretty much out of date by the time of printing, so they should be used only as a guide and with a grain of salt.
Some folks use the PCGS Price Guide. Keep in mind that these values are somewhat optimistic. Chances are the value of any particular set will be a little less than the value shown:
