That's the Model 520 Stevens. In typical condition they sell for around $150, really nice ones might get to $200-$225. There were military US-marked riot and trenchgun variants of the Stevens 520 than can reach over $1000. sales@countrygunsmith.net
I just received one of these guns for free but it is rusted pretty bad. I saw one in good condition for sale on gunbroker.com for $189. So my guess is that they are not high valued guns but may be more of a sentimental thing.
