I’m sure there are historians or historical societies that would love that stuff. Please don’t trash them. I’d recommend that you go to the AskHistorians subreddit and ask who would want them. I’ve seen people ask similar questions there and they seem to usually find a good home for the stuff. It would just be a little more effort than throwing it away but could mean a lot to future generations of historians.
