Topic: Is it possible to find age and value of my Brown marble

[Smith2701]

I have recently bought a brown marble and have been trying to find the age of it. It was manufactured by valley. I have also been told can do by serial number but havent had any luck. It was also made with no scoring rails and the serial number is very low mostly all zeros except last 3 digits being 180. Can anyone help me with this? I would like to add scoring rails but dont know if I should.

If you post a picture...or link to a picture...there is a good chance someone can help narrow down year.  You did not mention if it was coin-op ?

Value as a collectible?  Probably not much.
Value as a learning tool?  Plenty.
