What a great book!! My siblings, parents and in-laws have all been collecting the quarters. I am going to give your book to all of them for Christmas! Thank-you for writing it! I haven't seen my in-laws collection, but they have to collect quarters from both mints. They have an easier time with the Denver's as they live in Phoenix - so I try to find the Philly's since I live in Florida. It's been a lot of fun and your book is going to be the perfect ending for all of us.
