Should I be insuring these HOF photos from 1960s?

Back in the 1960s my dad produced three films for the baseball Hall of Fame. When showing the early t206-era players, of course, there wasn't that much good footage then known, so he resorted to using still photographs. What they did was make a print from the vintage print. I still have a few of the original vintage prints, which I posted some images of a few months ago on another thread.

My question now is, is there a market for the prints they made in the 1960s? Should these photos (I have about 50 or so) be insured? Some are marked up either for publication or for the film, as you can see from the small sample below.

This first one is of a photograph dated 1917 of Cobb. I do have the original print, dated 1917, I posted it on previous thread. This one is marked up, as you can see


Most of them look more like this:


Then there are a couple of prints of early photos made from the original photos used in the t206 series. I guess that makes them 3rd generation, at least.
