Real finds.
Real results.
The playable collection contains 732 individually identified completed auction results. Each photograph links to its original lot, names the auction house and credits Auctionet. Item names are short plain-English descriptions written from each lot’s catalog entry; the original lot page has the full description. This is an independent game, with no auction-house endorsement.
What the number means
We compare hammer prices, excluding buyer fees, tax and shipping. To compare currencies fairly, the game shows a rounded US-dollar equivalent. Each result’s details show the original amount and currency, sale date and the historical reference-rate date. We never substitute an estimate, asking price or unsold listing. A title can describe a whole group or pair.
Historical conversions use the European Central Bank’s reference-rate series through Frankfurter. We use the latest published rate on or before the sale, carrying the previous business-day rate across weekends. These are reference conversions, not the actual exchange rate a buyer paid. Displayed ties accept either answer.
Auctionet and the houses
Our initial Auctionet collection contains 9,414 eligible results from 82 houses, sold November 7–12, 2026. These are predominantly European auctions, open to an international audience; they are not a census of US auction results. Additional verified records are added through bounded recent-result checks and category backfill. A large source archive does not mean every record has been imported.
Auctionet’s published reuse policy permits reuse with a link and attribution to both Auctionet and the originating house. We retain that credit directly on the photograph’s card, including before a guess. Rights remain with their owners. We exclude Balclis because separately published image terms require further permission, along with records that lack a qualifying photograph, final result, attribution or historical conversion.
The photograph is the item
We serve the source’s own photograph, unchanged, inside a consistent contained card. We do not generate replacement objects, erase wear, invent signatures or redraw details. HammerHigher caches verified original bytes to make play fast and avoid contacting the source from your browser. The reuse policy is checked during refresh; a material change pauses the source for review.
Other sources
We are evaluating direct contributions and licensed feeds from independent US auction houses. LiveAuctioneers and Invaluable require additional permissions for reproduction; their public results are not permission to redistribute photographs. Earlier Rago/Wright-family records are retained only to preserve historical game references and saved-find metadata. Their uncleared photographs are not distributed with this release or chosen for new games.

Open a revealed result and choose “Something look off?” to flag its price, photograph, details or rights. We keep source URLs and lot numbers so a human can review corrections. Historical results are entertainment data, not current appraisals.
