Warren Giles Baseballs in original boxes

[LuckyLuke]

I was wondering if anyone can help me out with the Warren Giles baseballs in the images that follow.

How does one date these baseballs merely by looking at the boxes?
Are the baseballs in the white and yellow boxes Canadian? Art they more rare?

Thank you for all your guidance.

Lucky.

They won't help with the yellow boxes, which I do believe are the Canadian version, but I haven't handled enough to say which president's stamp the balls inside may carry. In my limited experience with the Canadian versions, they are scarcer, but generally don't bring as much when it comes to selling. Why? I don't know. Perhaps because they're not quite what folks are "used to" when it comes to vintage balls?

I am always amazed with the knowledge of fellow board members.

Thank you very much for your valued opinions as always.
