Inherated Trains

Hello all

I have a box of Brass trains and have been looking for SN# or manufacture dates. They are in there boxes with original wrapping one is a Santa Fe 4-8-4 I cant find a SN# anyware I see $59.50 on the box. they are black but on the under side i can see the brass they are heavy well the engine is anyway. I want to find there value but from what I have seen I need dates there is no paper work either. Any help or advice will be appreiciated I want to sell them so some one can enjoy them instead of them wasting away. in my attic another one is Colorado & Southern HOn3 2-8-0 its unpainted brass they are all United Tokyo model trains

Thank you Randy “Hambone”

I do not recognize these engines. Perhaps you would find better assistance on the model railroader forum?
