Dear Stacey,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a volumes of an complete work edition of the works of William Shakespeare. This covolute includes just the volumes 1, 3, 6, and 8. No frontispice is visible but the decor of the books are a hint that these were made in the second half of the 19th century. This colvolute is sadly not interesting for celloctors because it is incomplete and the books are in damaged condition.
An estimation would be between 0 to 15 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With kind regards,
Georg
