My father bought the full 1976 Freedom Train set (lionel O scale I believe) in 1976. He has kept them all in the boxes for the last 33 years. These are fairly large trains. He was asking me about the value of these trains over the last few weeks. Being a forumer I decided to seek out and ask the experts. He has tons of other trains that are all between 30 and 50 years old. But lets start with this first question and work our way up. I've posted this on other forums to see what kind of info I can scrape together. Thank you in advance for any help.
