I bought this as a Christmas gift for my 6 yr. old son. When he started learning about money last year in school, he was fascinated with the difference in each quarter and I thought this would be a great way for him to start a collection. Unfortunately, for the price, you get what you paid for on this one. The book in itself is sturdy but the slots to insert the coins is rather flimsy and you can see the imprint pushing through the cover when the book is closed. I found a much nicer book with a map of the United States at a bookstore for a dollar more than this one. I'd suggest looking for alternatives if you're buying this for children.
