Whether they are worth keeping or not is entirely up to you. If you like pennies in your collection these are fine examples of very red ones. For penny collectors red is definitely better than red/brown or brown (like your '64). And of course the farther back you go, the harder it is to find red ones. But these aren't a particularly rare year. So there is not a whole lot of value. But I would definitely put them in 2x2 flips, to keep them form toning. And the flips in a Whitman (or similar) 2x2 holder.
