Roman and ancient coin auctions: denarii, sestertii and more, searched at once

Roman coins are one of the most affordable entry points into ancient numismatics, common bronze issues from the later empire can be found for modest sums, while coins tied to a specific emperor, mint or historical event, especially in silver or gold, command serious premiums. Beyond Rome, Greek, Celtic and other ancient coinages form a related and equally collected field.

Why Roman and ancient coin lots get missed

General sellers, especially those clearing an estate with a mixed metal detecting find or old collection, often can't identify the emperor, mint or type on an ancient coin, and list it generically as "old bronze coin" or "ancient coin, uncleaned," hiding real value.

One search across every platform: including a numismatic specialist

Auction Bid Assistant's free browser extension searches the-saleroom, EasyLive, Bidspotter, Invaluable, NumisBids, iCollector and LiveAuctionWorld simultaneously, alongside eBay. NumisBids is itself a platform dedicated entirely to coin and banknote auctions worldwide, so a single search here already reaches specialist numismatic sales as well as the general auction houses where mis-catalogued lots hide. Search an emperor's name, "denarius," "sestertius," "ancient coin," or "Roman coin" generally and results return across all of them, with images, estimates, current bids where shown, and sale countdowns, sorted by platform in tabs.

Real results for "Roman coin": genuine ancient Roman coins including a rare Herennia denarius and uncleaned detecting finds, found in one search.

It works by searching from inside your own browser, the same as opening and searching each site yourself, just done in seconds. Nothing is stored on our servers, permissions are minimal, and the extension never places a bid on your behalf.

Alerts: for the emperors and types you collect

Save a search (an emperor's name, a coin type, or "Roman coin" generally) and get emailed the moment a new lot matches it, across all covered platforms including eBay and NumisBids, rather than relying on remembering to check each one.

Want to try before installing?

The same search box works on this website with no install at all for eBay, iCollector, LiveAuctionWorld and Featured Auction catalogues, a quick way to see matching Roman or ancient coin lots before adding the rest of the platforms via the extension.

Built for how ancient coin collectors actually work

Save any lot with one click from search results, export your shortlist as a printable PDF or CSV before a sale, and on the day itself the optional live bridge feeds the auctioneer's asking price into the free bid calculator, so your maximum (with buyer's premium and VAT included) is always in front of you.
