A digital copy of a book is identical in value to a printed copy.
Simple example:
Actual book from 1732 (rare, original, older than your country): https://blackwells.co.uk/bookshop/product/The-Compleat-City-... -- yours for £1,258.00
A scan of the same edition of that book: https://archive.org/details/bim_eighteenth-century_the-compl... -- free. Nobody's paying any money for the digital copy.
I don't think you understand the book itself is a collectible object with rarity and value, regardless of the information it contains.
Digital copies can be altered at whim, as the only means to provide any sort of tracking or verifiability is through another external software system that itself has to be trusted.
