Oh that would be tough... But if you are in member of a same forum you can track on his posts and reputations though this is really not an assurance.
Like all collectibles the value depends on the number of people looking for the trains you have and how easy they are to find. Many Postwar, meaning after 1945 up to 1969 train sets are quite valuable and some have little value. Web sites for trains which gives you a good starting place. Condition is also very important, the better the condition the higher the value. If you have postwar train that are unopened you have quite a treasure. I have seen an unopened 1587s Girls set go for 31,000 while in normal condition they can sell for 1200.00.
