The 1st picture is a very common outer seal lid, looks like a quart size.
The 2nd picture is another very common quart lid that was Made in Canada , letters D F G Co, Diamond Flint Glass Co. There are earlier similar lids without the outer 3 circles made by Dominion Glass Co. The pint size is with the 3 outer rings is considered Rare.
