Sixbid: The Online Auction Portal Connecting Collectors to the World’s Coin Sales
For over two decades, Sixbid has served as a central meeting point for collectors, dealers, and auction houses, offering a single platform to browse, bid, and track numismatic sales globally. This review examines Sixbid’s history, features, reputation, strengths, and areas for improvement — helping you decide whether it’s the right tool for your coin-buying strategy.
A Pioneer in Online Auction Aggregation
Founded in the early 2000s, Sixbid.com was one of the first platforms to aggregate coin auctions online, giving collectors worldwide access to sales they might never have discovered otherwise. It was created to unite the fragmented auction landscape, offering a centralized space where multiple auction houses could present their catalogs to an international audience.
Over the years, Sixbid has grown to host hundreds of sales annually, from major firms like Künker, Stack’s Bowers, and Heritage to smaller regional auctioneers. The platform’s reach now extends across ancient, medieval, and modern coins, as well as medals, orders, and banknotes.
How Sixbid Works
Sixbid is both a catalog aggregator and a bidding platform. Auction houses can choose to list their sales on Sixbid in two main ways:
Core Features Include:
Reputation Among Collectors
Within the numismatic community, Sixbid is seen as a long-established, reliable hub. Many collectors use it as their first stop for checking what’s currently on the market, particularly for high-profile European and ancient coin auctions.
Positive comments often highlight the convenience of seeing multiple sales in one place and the ability to place bids without having to navigate multiple unfamiliar auction sites.
However, some users on forums have noted that the interface can feel dated compared to newer platforms like NumisBids. Others mention that while Sixbid’s coverage is broad, the lack of integrated historical price data means it works best as a shopping window rather than a research archive.
Strengths That Keep Sixbid Relevant
Areas for Improvement
Who Should Use Sixbid
Final Thoughts
Sixbid remains one of the most established and widely used numismatic auction portals in the world. While its interface shows its age, its reach, trustworthiness, and convenience make it a staple for many collectors’ auction routines.
If your goal is to stay on top of what’s available in real time — from ancient aurei to modern commemoratives — Sixbid deserves a spot in your bookmarks. For research into past prices, you may still need to pair it with databases like ACSearch or CoinArchives, but for discovering and bidding in live sales, it continues to hold its place as a valuable tool in the collector’s arsenal.

How Sixbid Works
Sixbid is both a catalog aggregator and a bidding platform. Auction houses can choose to list their sales on Sixbid in two main ways:
- Bid on Sixbid: Collectors can register directly on the site and place absentee bids without visiting the auctioneer’s own platform.
- Redirect to Auction House: In some cases, Sixbid serves as a showcase and link, sending bidders to the host’s website for registration and bidding.
Core Features Include:
- Searchable Auction Listings: Filter by auction house, category, country, or keyword.
- Lot Pages with Images and Descriptions: High-quality images, estimates, and detailed attributions.
- Auction Calendar: A chronological view of upcoming and past sales.
- Dealer Directory: Profiles of participating auction houses.
- User Account Tools: Saved searches, bid tracking, and notification options.

- Additional Research Tools: Incorporating realized prices or cross-platform provenance tracking could increase its value beyond active bidding.
Who Should Use Sixbid
- Active Bidders: Those who participate in auctions from multiple houses and want a single login.
