Dear Jonathan, Thank you for contacting Mearto with your appraisal inquiry again. The presented object appears to be the complete works of Alexandre Dumas published as an Edition De Luxe from The Nottingham Society. Volume 1 and probably also volume 12 are missing. Comparable objects were recently offered and sold on the international auction market. This piece is in good condition and no severe damage is visible in the images provided. A fair market estimation would be between 90 to 150 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
