winchester 1897 riot what's it worth

[lgv800r]

Hello all this is my first post, sorry I don't have something more to contribute at this time but I have a question for anyone that can help. As the title states I have a win.97 riot shot gun in really nice shape(or so I believe). It has matching numbers 841,xxx what's it worth and about when was it made?
Thanks

BTW I'm reposting this here because some fellow forums members said this a better spot.
