Found some marbles in my attic, are they valuable?

I found 30 or so marbles in my attic, I have no idea how old they are. Anyone have any thoughts as to age or value?

those appear to be vitro with a couple alley agates thrown in...typical stash from the 50s...not much val;ue there but nice vintage marbles...the ones with the red patch are all reds...
