ACSearch: The Numismatic Price Archive Every Collector Should Know
In a hobby where knowledge is often the difference between a bargain and a blunder, ACSearch has become an indispensable tool for serious coin collectors and dealers. With millions of auction results spanning decades, this Swiss-based platform offers a vast historical record of coin prices, images, and descriptions. This review explores ACSearch’s role in numismatics, its features, community perception, and how collectors can get the most out of it — while also considering its limitations.
From Research Project to Industry Standard
Founded in Switzerland in the late 2000s, ACSearch.info began as an ambitious attempt to compile coin auction results from around the world into a single, searchable database. The goal was simple but powerful: allow collectors to research provenance, pricing trends, and rarity without having to manually sift through hundreds of auction catalogs.
Today, ACSearch has archived results from over 14,000 auctions held by more than 440 auction houses worldwide. Whether you’re tracking ancient Greek staters, medieval thalers, or modern commemoratives, chances are ACSearch has multiple past sale records for the coin you’re interested in.
How ACSearch Works
The platform operates primarily as a historical price archive, indexing both textual descriptions and images from auction catalogs.
Reputation and Community Perception
Among active collectors, ACSearch is widely recognized as a research powerhouse. On forums like CoinTalk and NumisForums, it’s frequently mentioned alongside NumisBids — with the distinction that NumisBids is preferred for upcoming auctions, while ACSearch dominates in past sales research.
Many professionals, including dealers and catalogers, rely on ACSearch to verify attributions, track provenances for high-value coins, and gauge price trends for appraisal purposes. For ancient coins in particular, ACSearch is often the first place experts look to confirm authenticity and market history.
However, some hobbyists express frustration at the paywall for realized prices, noting that other databases offer partial price history for free. Still, most agree that the subscription cost is modest compared to the value provided for serious collectors and market participants.
Strengths That Make ACSearch Invaluable
Areas for Improvement
While ACSearch is already a top-tier tool, there are a few ways it could enhance its user experience:
Who Should Use ACSearch
Final Thoughts
ACSearch has firmly established itself as the go-to historical price archive for the numismatic world. While its paywall for realized prices may deter casual collectors, its combination of breadth, depth, and image quality makes it an essential subscription for anyone serious about buying, selling, or studying coins.
In an age where auction results can disappear from the web in a matter of months, ACSearch’s archival mission ensures that vital market and provenance information remains accessible. For collectors who understand that knowledge is as valuable as the coins themselves, ACSearch is not just a convenience — it’s a competitive advantage.

How ACSearch Works
The platform operates primarily as a historical price archive, indexing both textual descriptions and images from auction catalogs.
- Search Engine: Users can search by keywords, ruler names, mint marks, denominations, date ranges, and even auction house names.
- Image Database: Nearly every archived lot includes high-resolution photographs, making it possible to compare coins visually for condition and style.
- Realized Prices: For most entries, the final hammer price (plus buyer’s premium, if available) is recorded, giving collectors a clear picture of market value at the time of sale.
- Auction House Links: Each record includes a reference to the original auction, which can be useful for verifying provenance.

Strengths That Make ACSearch Invaluable
- Massive Coverage: Millions of records from hundreds of auction houses, covering all eras and regions.
- Image-Rich Database: High-quality photographs make it possible to study coin dies, styles, and wear patterns.
- Provenance Tracking: Essential for verifying pedigrees, especially for coins with legal or cultural heritage considerations.
- Advanced Search Tools: Subscribers can filter by narrow parameters to pinpoint exactly the type of coin they’re researching.
- Longevity: Years of archived results make long-term market analysis possible.
Areas for Improvement
While ACSearch is already a top-tier tool, there are a few ways it could enhance its user experience:
- Mobile Optimization: The current interface is usable on phones, but a dedicated mobile app would greatly improve accessibility for on-the-go research.
- User Tutorials: Some of the advanced search syntax is underutilized because new users aren’t aware of it — a built-in guide could help.
- Flexible Access Options: Offering limited free price history (for older sales, for example) could encourage more casual users to upgrade to paid plans.
Who Should Use ACSearch
- Advanced Collectors: For deep provenance research and understanding market trends in their specialty.
- Dealers and Auctioneers: For catalog preparation, valuation, and avoiding duplicate attributions.
- Historians and Researchers: For sourcing primary visual and descriptive data on coins across centuries.
- Serious Investors: To verify price history before making high-value acquisitions.
