Jesus of Nazareth rare book.

I have a book called Alpheus von Nazareth. by J Joseph, dated 1892.  In English, this would be Jesus of Nazareth.  I have not been able to find another book like this on the internet.  I have come across many books that say they have been translated from the original version of German 1892.  This book is in German.  I would love to have it evaluated to see what it is really worth, and perhaps it should be in a museum somewhere.  The book is in good condition, however there is two pages that have the top right of it missing, but does not affect the reading as it does not touch the words.  It is in very condition considering how old it is.
