Dear Melissa,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a four-volume edition of Don Quixote by Miguel de Cervantes. This edition was translated by Jarvis and printed by W. Wilson in 1821.
Comparable objects were recently offered and sold on the international auction market.
This piece is in medium condition and no severe damage is visible in the images provided.
A fair market estimation would be between 150 to 300 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards,
Gregory
