As you can see, this is my first post. I'm admittedly not a coin collector but my grandfather recently gifted me a handful of US Treasury Mint sets dating back to 1961. All are still in their original protective plastic, in their separate compartments. I've done some searching online to find out how much they might be worth but it's difficult to say because I don't know how much credence I can put into some random website I've found with values on it. I've attached a screen shot of the file he sent me with values as he found with his research, but I'm not sure how he found those. If anyone wants a picture of any of them, I'm happy to post here. What should my next step be? Should I bring them to a precious metals dealer in town? Or should I try ebaying them all separately? Do I have any sets that someone here is particularly looking for? I'm greatly appreciative of any help given here!
