Your husband has a decent collection for sure and those are worth quite a bit these days. I managed to squirrel some stuff away over the years including cars and comics. The comics I have over 7000 war comics all boxed away and hoping one day they will be fairly valuable. Early ones are from 1952 and you just don't see them anymore.
Still have some working parts of his train set as well, cars are brought out every couple of years to dust and reminisce.
Never collected comics, not something our parents allowed us to purchase, books yes have some book collections from back then as well.
Very early comics should hold good value, enjoy marketing them, or passing down to children one day.
