reuse 50 yrs old valves or not?

heatingFun

I am planning add zones and modify existing pipe setting. I am thinking put two valves on each CI baseboard. I have about ten 50 yrs old  shut-off valves from the existing piping. Should I reuse them or replace them with new ball valves?



Shut-off valves with that age are still good enough for another 20yrs?

Probably not worth it, but if they still turn.....
