My father just passed and I found his old Sax I was wondering if someone could tell me what year it is and its worth? It is a CG. Conn Pat 1914 1119954 M148820 L
The serial # 148820 dates it to about 1925. Fully restored it has a worth around $1200 or so, but it looks like it has been sitting for awhile and most likely needs to be restored to get that amount. If you don't plan on playing it yourself, I would just sell it as-is and get what you can for it.
A good shop using quality materials is going to charge you $800 - $1000 to take it apart, clean/polish it, and replace all pads, corks, and felts, and give it a good regulation.
