I have found this letter attached to a book, title is, reports of the Silver Commisions of 1876 ( being a reprint of Senate Report No. 703, 44th Congress, Second Session) Washington: Government Printing Office. The letter was attached to the book by our ..Ancestor . I have had no luck finding the value.if any .i will show the letter in the picture. The book has nothing on the cover. Who knows if the picture ever loaded. So frustrating
