These are large sized aspirin tins which for some reason are not nearly as sought after (or valuable) as the small sized tins. 

Aspirin tins are highly collectible and believe it or not I have seen one rare tin sell for over $500.00 (it had a picture of a bi-plane or a zeppelin on it) to see them sell for $100.00 is not uncommon. None of these are super rare but a few of them are not seen too often. Note that Anacin (or An-a-cin) had no aspirin in it to begin with. If you look closely they tried all sorts of differing combinations of ingredients to increase effectiveness but all ended up containing simply aspirin. The store counter displays  that contain aspirin tins sell well and you can see a bunch of them on pages at the end of the site “Displays and their tins”.
