U.S. Law Book Returned 143 Years Late

From the Law Librarian Blog:

"UPI is reporting that an 18th century law report volume, valued at $1,500, has been returned to the North Carolina Supreme Court 143 years after it was stolen (apparently by a Union soldier). The work, published in 1708, is "Report of Divers Cases in Pleas of the Crown Adjudged and Determined; in the Reign of King Charles II." There are two clues to the book's origin: (1) an unsigned inscription "Obtained in July 1865 at Raleigh, North Carolina," and (2) an inscription signed by Quentin Busbee, who served as the North Carolina Supreme Court reporter in 1853. Kudos to the librarians at Indiana University Library who tracked down the rightful owners after receiving the volume from an anonymous donor".

How high should the late fee for something like that be?
