Louis Marx Train Set #50325

Mary,

I don't have my copy of the Marx Sets reference book with me at the moment, but this sounds like a late-'60s/early '70s near-top-of-the-line set pretty typical of its times.  I suspect it has had cars added to it or perhaps a second set is partially present.  There is a lot of play opportunity there, as is also typical of Marx sets.

As for monetary value, well, the big variable is condition.  Pics would help us to evaluate it, but I can guarantee you and your busband will not retire on the prceeds should he choose to sell it ;-) None of the pieces is particualarly scarce or hard to find.  If it has been played with, no doubt there will be evidence in the form of nicks, scratches, maybe broken small parts.  Dust, rust, and so forth will reduce the raw market value.  On the other hand, having the box is a great plus!

You don't mention a transformer; is it present?

If you have any interest at all in having a train, you'll get far more pleasure out of cleaning it up and playing with it than you will from selling it.  Unless it is pristine, figure on getting maybe enough for a good steak/seafood dinner with drinks for two out of the sale.

All that said, if you post pics, we can be more precise.
