If you enjoy shooting, then I would say to keep them and pass them to another generation. I have my great-grandfathers 1884 Trapdoor Springfield, and still shoot and hunt with it. I honestly almost cried a little when my dad handed it to me and told me to 'hang on to it' about a year before he passed.
Your kids will be proud to own either of those rifles. But if you do end up selling them, look up the price in several locations, then add some sentimental value to them, and don't take the first offer
