Gavelogue, the object passport for collectors

Why it surfaced

Gavelogue looks beyond the hammer price, combining buyer’s premiums, tax scenarios, shipping, handling, and duties into a labeled cost range. Its passports and market examples turn the usually scattered paperwork of collecting historic objects into a living record—an unusually thoughtful piece of software for a very specific audience.

A collector’s tool that estimates an auction lot’s likely all-in cost and preserves its sources, questions, and provenance.
