I think im doing this right...(new guy)

I have an ithaca 10 ga double barrel shotgun with hammers and would like to know more about it.
History , year made , Is it worth anything , Is it too old to shoot? I understand I need to find some low brass to shoot in it if so. Do I have a rare gem or just some old junk?
I found the numbers on the shotgun but being that I'm at work I don't remember what they were. 4 digits... Just don't remember them. Will post later.

Thanks for all your help
