Once the paint is removed from the working surfaces, that would be a good homeowner anvil for casual use. If you were to use it often for blacksmithing work, then it would need a lot of work to make it serviceable for that purpose. There's a bit of a sway in it's back that would have to be minimized and some possible pitting that would have to be addressed.
As for price, well we would need to know how much it weighs and if there are any cracks on the sides that we can't see before we could throw out some credible numbers.
NEVER use an anvil for beating cold metal.
