The Method applied to Incunabula
Incunabula — books printed before 1501 — face moderate counterfeit pressure (sophisticated facsimiles exist, anachronistic paper and type betray modern fakes) and extreme valuation variance (identical editions differ 10–50× by condition, provenance, completeness). The method begins with three gates: verified collation against the bibliography, paper and type coherence with the claimed period, and contamination mapping — every scholarly or dealer hand before yours has already extracted margin.
The Method's take
The counterfeit-pressure law applies: high-value incunabula attract skilled facsimiles printed on old paper or chemically aged; paper watermarks, type wear patterns, and binding materials must align with the stated date and press (verify technical dating with a rare-book expert or institutional catalog). The genuine-find law is statistical reality: untouched estates and non-specialist sources yield the only bargains; anything offered by a known antiquarian already carries full scholarly markup. The affordable-loss rule is absolute: above €5,000–10,000, a written opinion from a recognized rare-book authority comes before purchase — the market pays certification, not your correctness. The non-comparability principle decides margin: census rarity (ISTC, GW, national union catalogs) and condition separate a €2,000 copy from a €200,000 one of the same title.
The math
A wrong attribution (buying a 16th-century book believed incunabulum, or a facsimile believed original) typically costs €3,000–30,000 in dead capital and reputational damage. A collation error (unknown incomplete copy, missing leaves or replaced sections) costs €5,000–50,000 in unrecoverable discount at resale. The 24-hour pass is €100; the annual pass €3,800. One avoided mistake pays for years of access.
