Do a web search on Curio & Relic, look for dealers like Century, or AIM, and you'll find many of these guns being offered for sale nowadays. Most are in fair shape, and they're reasonably priced at under $100.
These are shootable guns. The ammo, however, isn't cheap.
If yours is sound (get it checked) and without import marks, it might be worth $150-$200, but unlikely that its worth much more than than. (I'm guessing, here, so don't hold me to it.)
If you're interested, there are a number of lists (discussion groups) dedicated to C&R weapons, and this gun is discussed from time to time. Its a whole different world of weaponry. (Just got C&R license a few months back, and bought my first C&R handgun recently: a cz-50, a sweeting shooting little .32 auto. I was surprised by its accuracy.)
