Q: Hi – My mother recently gave my 7 year old the attached book (Treasure Island). He is very fond of it and carries it everywhere. I am worried that it may be more valuable than she readily is aware and should be reshelved. Could you possibly take a look and let me know the history in regards the book?

A: Your book was published in 1899 as part of the Sanspareil Series.

It only has nominal value so carrying it around won’t hurt its value.
