Q: I was wondering if you could tell me how old this book is and possibly how much it is worth

A: Your book was published in 1901-1902.

See http://henryaltemus.com/series/series143.htm

It has only nominal value.

This book like many of the books from this series, the Love and Friendship Series and the In His Name Series during any one year had an unchanging pattern on the left of the front cover. On the right of the cover however was one of 16 different flowers. They can be seen at the series site noted above.
