Patine — Antique Identification by Auction Evidence
A planned iPhone app that identifies antiques and estimates their value from comparable auction sales, with each result tied to a sale house, date, price, and source link.
Field notes
Patine’s proposed workflow separates identification from valuation and ties the latter to comparable auction lots rather than a single generated estimate. Its sample uses five Bonhams sales, reports hammer prices separately from buyer-inclusive figures, and marks an excluded outlier with a reason. The site also describes Archive, Market, and Profit views for the same photograph. The homepage says the iPhone app is coming to the App Store, so these mechanics are presently documented rather than demonstrated here.
