Research experts, I need your help.....

[Tina]

My sister's co-worker brought me three boxes of really OLD books. Most of them are in really good condition, and I've been able to find out what most of them are worth.

There's one here, that I'm having trouble finding any information on. If there's anyone willing to help me find out what this book is worth-- I would greatly appreciate it.

Info available from the book:

Hymnal of the Evangelical Church
Word Edition
Eden Publishing House
Chouteau Ave
St Louis, MO

It is a black cloth bound book--Has the word Hymnal on the front in gold lettering. Edges of the pages are also gold. Dated 1917. Book is about 4x6 inches.

From what I've found on some of these other books, I may need to increase the insurance on the contents of my home while I have these in my possession. I had no idea that old books would be worth so much money!

Thanks for any help... it is greatly appreciated.
