Original (?)Star trek scripts etc - how do I find out more about them?

[Wallace]

My brother has some star trek scripts and signed photos. How does he find out if they are original, and, most importantly , what they are worth?

You could try somewhere like this .

Take a look at this! He might have something worth some money!!

Oooh thanks! I hope they are worth something, he could do with the money! They are the original series BTW dated 166/67

Our grandother gave them too him a few years ago. We're not sure whether she collected them or what.

One of the scripts says "file copy only - do not remove"

I mean dated 1966/67
