Valuation methodology for this type of work

For this category, precise identification of the edition (original, reprint, facsimile) and the physical condition (original binding, defects, missing plates) are crucial. Our AI is trained to recognise characteristic typographic markers (page size, edition statements, colophons, printer’s marks), then compares these findings with recent comparable sales. The specialist bookseller verifies the analysis before sending it.
