The book keeps its silver

Status: Anticipated · untested

Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

Medieval coinage was repeatedly debased; grain prices and wages absorbed those shocks slowly and messily. Join debasement history to book prices: books, being durable, resaleable, and easily identified, were priced like plate — as stores of bullion value — so their prices in actual silver grams should hold steady through debasement episodes while consumables lurch, and their nominal prices should re-mark to the new coin within a few years. A buyer treating the book as an asset repriced it the way he repriced a silver cup, not the way he repriced bread. If this holds, the book market doubled as a small bullion market, and pre-print book demand was partly a demand for a literate form of stored wealth.

Prediction clause (verbatim)

Primary clause (carries the verdict): across documented debasement episodes, prices of comparable plain books expressed in grams of silver stay within plus-or-minus 15%, while grain prices in silver over the same episodes swing by more than plus-or-minus 40%. Secondary clause: nominal book prices complete their adjustment to the new coin within 5 years, faster than recorded wage rates do.

Kill-dataset (verbatim)

the Schoenberg Database of Manuscripts (SDBM) — nominal price series joined to published coinage silver-content tables; the kill is a statistical event-study across debasement episodes.

Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior. Kills and priors are credited here, by name, as they come in.

Novelty / leakage triage

anticipated in the literature — this exact test has never been run

Books as durable, resaleable stores of literate wealth are documented (loan-chest collateral), and coinage debasement is well studied, but the event-study claim that book prices hold within +/-15% in silver grams through debasements while grain swings >40% and books re-mark within 5 years is un-run.
