so is it mainly experience that estimates value.

sweet not too encouraging

there is a whole bunh of different makers and models, heres one for ya: Bachmann 2-8-0 consolidation classic collectors series part # 53002 santa fe. i don't know what year these are from. is there a stamp or something on the trains to tell me? i don't think this has ever been out of the box so i'm not sure if i want to open it.

have a suitcase full of 20?? year old trains new in the box. i have no idea how to find a value for them.  any online guides?? any help would be appreciated. and dont tell me they are worth $20.00 and you would be doing me a favor by taking them off my hands.
