Vulcans are good anvils but the serious users sometimes shy away from them due to the cast/welded face combo. If you repeatedly whack something cast iron with a hammer, it's gonna break. Do the same with a section of railroad track and nothing is gonna happen except some chipping.
As for value, I have no idea. I don't sell anvils but a good price range is 2.00 per pound and that gets higher with larger/older anvils. That's not set in stone because collectors will pay much more for smaller or more elusive models.
You could easily put a value of at least 200.00 on it but I'm sure it carries much more sentimental value then monentary.
