Q: A book (The Prince of the House of David) in good condition is listed for over $2500.00 on (site deleted by me so as not to shame the seller).

I have no intention of buying it but what do you think is the value of the book?

A: This book is a reprint published as part of the Golden Treasury Series in 1899.

See: Henry Altemus Company – Golden Treasury Series 99

On a good day with all the stars and planets aligned, it might sell for $10-15. 

The description by the seller claims that the frontispiece is signed by the artist. This signature is a facsimile. See below.
