Share 'Vintage Silvertone guitar and amp/case at Garage Sale...What's it worth?'

Just picked this up as a garage sale.  Model 1448 guitar and amp case... guitar almost virgin with just a few stains.  Case has a couple of nicks, a cigarette burn and a hinge to be repaired.  Amp powers up, but just hums..... So, what's it work and is it worth taking to someone to fix the amp?  Oh, btw, I get it for $ 15.
