Capacitor voltage ratings

I kind of messed up and wasn't paying attention when I ordered some electro caps and got some 6.3V ones. Should I just toss these or any reason to keep them?

depends where they are in the circuit, some caps don’t see much voltage, I’d probably toss them anyway just in case they got mixed up with other caps later on and I accidentally used one. I am not a fan of caps potentially blowing up near my face
