"Caruso: Trade name used by the Crescent Firearms Company on shotguns made for the Hibbard, Spencer, Bartlett and Company of Chicago." - From the Hoosier Gunworks site.
Crescent made guns for shops - places like hardware and department stores - to sell and most of their guns were basic entry-level utility guns. They made huge numbers of guns and most of them got used hard. There just isn't the kind of collector interest it takes to drive the price up.
I could take a guess and say it's worth $75 or $150, but I don't really know.
