Old Book Hunter is an informational publication, not a solicitation to buy, sell, or invest.
This issue's five: a physician's treatise on wound care that turns out to be a footnote to the birth of modern economics, a nearly-forgotten French account of a Danish mission to India, the first illustrated English record of the Herculaneum excavations that helped ignite European Neoclassicism, a genuinely 18th-century chapbook of Robin Hood ballads carrying a striking rarity claim, and the 1780 book that helped convince Britain to stop packing prisoners into single filthy cells.
This issue's Hunter Lesson examines our bargain more closely to understand the sometimes significant pricing spreads between instances of the same book.
Hunter's lesson
Spread, Explained
This issue's Bargain — Quesnay's Traité de la suppuration, 1749 — turned up on eBay twice this week. Same title, same year, same publisher. One listing: $64. Another, from a respected French antiquarian dealer: $637. Ten times apart, same book.
A spread that wide always has one of two explanations, and they point in opposite directions. Either the cheap copy is genuinely worse — damaged, incomplete, misbound — and the price is just fair discounting for condition. Or the price has nothing to do with the book itself: a seller who doesn't specialize in rare books, doesn't know what they're sitting on, and just wants it gone. The second one is a real bargain. The first one isn't a bargain at all — it's correctly priced for what it is.
Telling them apart takes actual looking, not just reading the price. The $64 listing does have a real condition note — a fragile front board — and that's worth knowing. But a shaky board doesn't explain a 90% discount on its own. More telling: the same listing's own structured fields contradicted themselves, dating the book to the 19th century in one field and 1749 in another. And the photos settle it: what's pictured is unmistakably an 18th-century binding and text block, not a later reprint wearing an old date. Once the visual evidence confirms the book is exactly what it claims to be, a minor condition flag and a self-contradicting data entry read very differently than they would on their own — together, they're just the signature of a seller who wasn't paying close attention, not a book worth a fraction of the price.
We've seen this same pattern before with our Laborde pick in issue #1 — the identical book, listed by the same seller across different platforms at genuinely different prices. eBay, in particular, often functions as a clearance channel: a place sellers use to move stock quickly, priced for speed rather than pegged to what a specialist dealer would actually ask. That's not a flaw in the book. It's a discount for a quicker sale.
